Quick answer: The Growtopia “check your internet connection” VPN error is almost always caused by blocked or flagged IP addresses, not your actual internet. Switching IP, changing VPN server, or using a different network fixes it in most cases.
Growtopia is not a typical online game when it comes to networking. Unlike many modern multiplayer titles, it relies heavily on IP-based filtering and behavior analysis to control abuse, bots, and multi-account farming.
This means that when you see the error:
“Check your internet connection and make sure you are not using VPN”
it is rarely about your connection quality. Instead, it’s a signal that your network identity has been flagged.
Understanding this distinction is critical. Most users waste time restarting routers or reinstalling the game — when the real issue is tied to IP reputation, shared networks, or VPN detection systems.
What Is Growtopia (And Why It Has Strict Network Detection)
Growtopia is a sandbox MMO built around a player-driven economy. Unlike standard multiplayer games, it allows:
- Massive item trading systems
- Player-created worlds
- Real-time multiplayer interactions
- Economy-based progression
This open system has historically made Growtopia a major target for:
- Bot farms
- Account farming operations
- Automated currency generation
- Multi-account abuse
Because of this, Ubisoft has implemented strict backend systems that monitor connections at a network level.
According to Ubisoft’s official documentation:
This is the key reason why many legitimate players suddenly get blocked.
What the Error Actually Means (Critical Understanding)
This error message is misleading by design.
It does NOT mean:
- Your internet is down
- Your WiFi is broken
- Your device cannot connect
Instead, it usually means one of the following:
- Your IP address has been flagged or blocked
- You are using a shared IP associated with suspicious activity
- Your VPN server is blacklisted
- Your connection pattern looks automated or abnormal
In technical terms, Growtopia is rejecting your connection during the authentication or handshake phase, before gameplay even begins.
This is similar to how modern web security providers (like Cloudflare) evaluate IP reputation before allowing access:

Why VPN Users Are Affected the Most
VPN users are disproportionately affected by this error — but not for the reason most people think.
The issue is not that Growtopia “blocks VPNs” outright.
The real issue is how VPNs interact with IP reputation systems.
Most VPN providers assign users a shared IP address. This means:
- Hundreds or thousands of users share the same IP
- One bad actor can affect everyone
- The IP gets flagged or blacklisted
This is a well-documented issue in networking environments:
RIPE NCC – Carrier-grade NAT and shared IP environments
Growtopia treats VPN IPs similarly to CGNAT (Carrier-Grade NAT) environments — where many users appear as one identity.
Datacenter IP Detection
VPN servers typically run on datacenter infrastructure, not residential networks.
These IP ranges are publicly known and easy to detect.
For example:
Games often restrict these ranges because they are commonly used for automation and botting.
Connection Pattern Analysis
Growtopia doesn’t just look at IPs — it also evaluates how you connect.
VPN usage can introduce:
- Latency spikes
- Packet loss
- Frequent reconnects
According to Microsoft networking documentation, unstable connections can break real-time applications:
Microsoft – Network latency and performance tuning
This can trigger connection failures even if your VPN isn’t blocked.
Important: This Error Happens Without a VPN Too
This is one of the biggest misconceptions.
You can get the exact same error without using a VPN at all.
This typically happens when:
- Your ISP uses shared IP addressing (CGNAT)
- Your IP was previously used by another player
- Your network is flagged due to past activity
This explains why switching to mobile data often works instantly — you’re simply getting a new IP.

Why Most “Fixes” Online Don’t Work
If you’ve searched for this problem before, you’ve probably seen advice like:
- Restart your game
- Clear cache
- Reinstall Growtopia
These rarely solve the problem because they don’t address the root cause.
The real issue is almost always one of these:
- IP reputation problem
- VPN server blacklist
- Shared network restriction
- Connection instability
Until you fix the underlying network identity, the error will persist.
How This Relates to VPN Technology
VPNs are designed to hide your identity — but in gaming environments, this can backfire.
Depending on your setup, features like:
can directly affect how your connection appears to Growtopia.
We’ll go deeper into how to configure these correctly in the next sections.
What You Should Do Next
Now that you understand the real cause of the problem, the next step is to apply the correct fixes.
In the next section, we’ll go through:
- How to instantly test if your IP is the problem
- The fastest way to fix the error
- Which VPN setups actually work with Growtopia
Step-by-Step Fixes That Actually Work
Now that you understand the root cause — that this is an IP and network identity issue — we can move on to the fixes that actually solve the problem.
These are not random suggestions. Each fix targets a specific underlying cause of the Growtopia connection error.
Fix 1: Change Your IP Address (Highest Success Rate)
If your IP address is flagged, nothing else will work until you change it.
This is the single most effective fix because Growtopia blocks connections based on IP reputation.
Method 1: Restart Your Router
- Turn off your router for at least 60 seconds
- Turn it back on
- Reconnect and launch Growtopia
This works if your ISP uses dynamic IP assignment. When you reconnect, you may receive a completely new IP address.
Method 2: Switch to Mobile Data
- Disable WiFi
- Use 4G/5G connection
- Launch Growtopia again
If the game works on mobile data but not WiFi, your original IP is almost certainly flagged.
This is one of the fastest ways to diagnose the problem.
Fix 2: Switch VPN Server (If You Want to Keep Using VPN)
If you are using a VPN, your current server is likely blocked or flagged.
Switching servers gives you a completely new IP — which often bypasses the restriction instantly.
Best practices when switching servers:
- Choose a different country (not just a different server in the same region)
- Avoid overcrowded servers
- Try smaller or less popular locations
Premium VPN providers rotate IP addresses frequently, which reduces the chance of hitting a blocked one.
Recommended providers with large IP pools:
If you are using a free VPN, this problem is significantly worse due to limited IP availability and heavy abuse.
Fix 3: Change VPN Protocol (Very Underrated Fix)
Different VPN protocols behave very differently when it comes to speed, stability, and detection.
If your current setup is unstable or flagged, switching protocol can fix the issue without changing servers.
Recommended protocols:
- WireGuard – fastest and most stable (Learn more)
- OpenVPN (UDP) – best compatibility (Guide)
- IKEv2/IPsec – best for mobile (Explained)
Why this works:
- Some protocols are easier to detect
- Some cause higher latency
- Some handle packet loss better
If your VPN connection is unstable, you should also check:
Fix 4: Test Without VPN (Critical Diagnostic Step)
This step is not a solution — it’s a diagnostic.
Disable your VPN completely and try launching Growtopia.
Results:
- If it works → your VPN is the problem
- If it doesn’t work → your IP or network is flagged
This simple test tells you exactly where the problem is coming from.
Fix 5: Use Split Tunneling (Best Hybrid Solution)
If you want to keep your VPN active but still play Growtopia, split tunneling is the best solution.
This feature allows you to route Growtopia outside the VPN while keeping everything else protected.
Why this works:
- Growtopia sees your real IP (no VPN detection)
- Other apps still use VPN protection
This is one of the most effective long-term solutions.
Fix 6: Check DNS and Routing Configuration
DNS issues can break connections even when everything else looks correct.
Growtopia relies on proper DNS resolution to connect to servers. If DNS requests are misrouted, the connection fails.
What to do:
- Enable VPN DNS protection
- Clear DNS cache
- Avoid custom DNS unless necessary

Fix 7: Disable Kill Switch (Temporary Test)
A VPN kill switch is designed to block traffic if your VPN disconnects — but it can sometimes interfere with normal connections.
Try disabling it temporarily and test again.
If the issue disappears, your kill switch configuration needs adjustment.
Fix 8: Use a Dedicated IP (Advanced Fix)
If you keep getting blocked even after switching servers, the issue is likely shared IP abuse.
A dedicated IP gives you a unique address that is not shared with other users.
Benefits:
- Lower risk of bans
- More stable connections
- No shared reputation issues
This is one of the most reliable solutions for consistent access.
Quick Troubleshooting Flow (Use This First)
If you want the fastest possible fix, follow this order:
- Switch to mobile data
- If it works → your IP is flagged
- Restart router or change network
- If using VPN → switch server
- If still not working → change protocol
This process solves the majority of cases within minutes.
Advanced Issues That Can Cause the Error
If none of the basic fixes work, the problem is likely more advanced. At this point, you are no longer dealing with a simple VPN issue — but with how Growtopia identifies and restricts connections at a deeper level.
These cases are less common, but they are also the most frustrating because standard fixes won’t work.
IP Ban vs Device Ban (Critical Difference)
One of the most important things to understand is the difference between an IP ban and a device ban.
Growtopia uses both.
IP Ban
An IP ban means your current internet connection is blocked.
Signs of an IP ban:
- Game works on mobile data but not WiFi
- Works on another network
- VPN sometimes bypasses it
This is the most common scenario.
Device Ban
A device ban is more serious. It means your hardware has been flagged.
Signs of a device ban:
- Game doesn’t work even with VPN
- Doesn’t work on any network
- New accounts get blocked instantly
According to Ubisoft support:
IP or device bans can affect access even if you did not violate rules directly
This means you can be affected by previous users on the same device or network.
Carrier-Grade NAT (CGNAT) – Hidden Cause for Many Users
Many users are affected by CGNAT without realizing it.
Carrier-Grade NAT is when your ISP assigns the same public IP address to multiple users.
This creates a situation similar to VPN shared IPs.
Why this matters for Growtopia:
- You share an IP with other players
- Someone else can get the IP flagged
- You get blocked even if you did nothing wrong
This is officially documented in networking standards:
RIPE NCC – Carrier-Grade NAT explained
How to detect CGNAT:
- Your public IP changes frequently
- You cannot port forward
- Your ISP uses shared infrastructure
If you are behind CGNAT, switching networks or using mobile data often fixes the issue instantly.
ISP-Level Filtering and Restrictions
In some cases, the issue is not Growtopia — it’s your ISP.
Some ISPs apply filtering or routing policies that interfere with game servers.
Common problems include:
- Blocked ports
- Traffic shaping
- Routing issues
This can cause Growtopia to fail during connection setup.
If your VPN works but your normal connection doesn’t, this may be the cause.
You can test this by:
- Using mobile data
- Switching to another ISP
VPN Detection Beyond IP (Deep Inspection)
Modern systems don’t rely only on IP addresses — they also analyze traffic patterns.
This includes:
- Packet structure
- Connection timing
- Protocol signatures
Some VPN protocols are easier to detect than others.
For example:
- OpenVPN can sometimes be fingerprinted
- WireGuard is harder to detect but still identifiable
More technical background:
This is why switching protocol can sometimes fix the problem even when the IP stays the same.
Connection Instability (Often Misdiagnosed)
Even if your VPN is not blocked, an unstable connection can cause the same error.
Growtopia requires a stable connection during login. If packets are lost or delayed, the connection fails.
According to Microsoft’s networking documentation:
Latency and packet loss can break real-time applications
Common causes:
- Weak WiFi signal
- Overloaded VPN servers
- Background network usage
If your VPN is unstable, fix that first:
Firewall and Security Software Blocking the Game
On PC, local firewall or antivirus software can block Growtopia’s connection.
This can trigger the same error message even if everything else is working.
What to check:
- Allow Growtopia in firewall settings
- Disable antivirus temporarily
- Check router firewall rules
This is less common but still a known cause.
Temporary Server-Side Issues
Sometimes the problem is not on your end at all.
Growtopia servers can occasionally experience:
- Overload
- Maintenance downtime
- Connection bugs
When this happens, users may receive incorrect error messages — including VPN-related ones.
If multiple players report the same issue at the same time, it is likely server-related.
Corrupted Game Files or App Issues
In rare cases, the issue may be local to your device.
This includes:
- Corrupted game files
- Outdated app version
- Broken cache
Possible fixes:
- Update the game
- Clear cache
- Reinstall Growtopia
This should only be done after ruling out network issues.
Key Takeaway Before Moving On
At this point, you should understand that the Growtopia VPN error is not a simple connectivity issue.
It is caused by a combination of:
- IP reputation systems
- Shared network environments
- VPN detection mechanisms
- Connection stability factors
Fixing the issue requires targeting the correct cause — not applying random fixes.
In the final section, we’ll cover the best long-term solutions and how to prevent this issue from happening again.
Best Long-Term Solutions (How to Avoid This Problem Completely)
If you’ve fixed the Growtopia VPN error once, you probably don’t want it coming back again.
The reality is that this issue is not random — it’s predictable. If you understand what triggers it, you can avoid it entirely.
Use a High-Quality VPN With Clean IP Pools
Not all VPNs are equal when it comes to gaming.
Low-quality or free VPNs reuse the same IP addresses heavily, which increases the chance of bans and connection issues.
Premium providers maintain larger IP pools and rotate them more frequently, reducing the risk of hitting a flagged address.
Recommended options:
- NordVPN – best balance of speed and IP rotation
- ExpressVPN – most stable connections
- Surfshark – budget-friendly with large server network
- CyberGhost – optimized servers for different use cases
These providers consistently perform better in environments where IP reputation matters.
Use a Dedicated IP for Maximum Stability
If you play Growtopia regularly, a dedicated IP is one of the best long-term investments.
Unlike shared IPs, a dedicated IP is used only by you.
Learn more about dedicated IPs
Why this works:
- No shared reputation issues
- No risk of other users getting your IP banned
- More consistent connection behavior
This almost completely eliminates VPN-related detection problems.
Use Split Tunneling for Gaming
Split tunneling is one of the most effective solutions for gamers.
It allows you to exclude Growtopia from the VPN while keeping everything else protected.
Benefits:
- No VPN detection for Growtopia
- Full VPN protection for other apps
- Better performance and lower latency
This is often the best balance between privacy and usability.
Optimize Your VPN Setup (Avoid Common Mistakes)
Many users unknowingly create problems through incorrect VPN configuration.
Make sure you:
- Use stable protocols like WireGuard or OpenVPN
- Avoid overloaded servers
- Keep your VPN app updated
Technical breakdowns:
Choosing the right protocol can significantly improve connection stability.
Fix Underlying VPN Issues
If your VPN is unstable, Growtopia will continue to fail regardless of IP quality.
Common issues include:
- VPN keeps disconnecting
- VPN not working on public WiFi
- VPN not working on Android
- VPN not working on iPhone
Fixing these issues ensures consistent connectivity.
Final Verdict
The Growtopia “check your internet connection” VPN error is not actually about your internet.
It is caused by how the game evaluates:
- Your IP address
- Your network environment
- Your connection behavior
The most effective fixes are:
- Changing your IP address
- Switching VPN servers
- Using a reliable VPN provider
- Ensuring a stable connection
If you want a permanent solution, combining a high-quality VPN + dedicated IP or split tunneling is the most reliable approach.
