"Failed to Connect to Server"
This is the most common multiplayer error in Hytale Early Access. Here are the main causes and solutions:
Quick Diagnosis Checklist
- ✅ Both players have Hytale updated to the same version
- ✅ Server host's firewall allows Hytale/VPN software
- ✅ Using the correct IP address and port (default: 5520)
- ✅ Server is actually running and hosting
- ✅ Not exceeding max player limit
Solution 1: Virtual LAN (Recommended)
Best for: Playing with friends without port forwarding hassle.
Method A: Radmin VPN (Free & Easy)
- Download Radmin VPN: Both host and players download from
radmin-vpn.com - Create Network: Host creates a new network and sets a password
- Join Network: Friends join using network name and password
- Get Virtual IP: Host checks their Radmin VPN IP (e.g.,
26.xxx.xxx.xxx) - Start Server: Host starts their Hytale server (default port 5520)
- Connect: Friends use "Direct Connect" in Hytale with
HostRadminIP:5520
Method B: Hamachi
- Download LogMeIn Hamachi (free for up to 5 players)
- Host creates a network, friends join
- Use host's Hamachi IPv4 address (shown in Hamachi client)
- Connect in Hytale:
HamachiIP:5520
⚠️ Common Hamachi Issue: If you see yellow or red status lights, check your firewall or try restarting Hamachi.
Method C: Tailscale
Modern, secure VPN alternative. Download from tailscale.com and follow similar steps.
Solution 2: Firewall Configuration
Windows Firewall often blocks Hytale or VPN software. Here's how to fix it:
Adding Hytale to Windows Firewall
- Press Windows Key + R
- Type
firewall.cpland press Enter - Click "Allow an app or feature through Windows Defender Firewall"
- Click "Change settings" then "Allow another app..."
- Browse to Hytale installation folder (usually
C:\Program Files\Hytale\) - Select
Hytale.exeand add it - IMPORTANT: Check both "Private" and "Public" boxes
- Repeat for Radmin VPN/Hamachi if using virtual LAN
⚡ Quick Test: Temporarily disable Windows Firewall to see if it's the issue. If server works with firewall off, add exceptions above, then turn firewall back on.
Solution 3: Port Forwarding (Advanced)
Use this if: Virtual LAN doesn't work or you want public server accessibility.
Port Forwarding Steps
| Port Number | 5520 (UDP) |
| Protocol | UDP (some routers may need both TCP/UDP) |
| Forward To | Your PC's local IP (e.g., 192.168.1.xxx) |
Step-by-Step:
- Find Your Local IP:
- Press Windows Key + R, type
cmd - Type
ipconfigand find "IPv4 Address" (e.g., 192.168.1.10)
- Press Windows Key + R, type
- Access Router Settings:
- Open browser, go to your router's IP (usually
192.168.1.1or192.168.0.1) - Login with router credentials (check router label if unknown)
- Open browser, go to your router's IP (usually
- Create Port Forward Rule:
- Find "Port Forwarding" or "Virtual Server" section
- Add rule: External Port: 5520, Internal Port: 5520, IP: Your Local IP, Protocol: UDP
- Save and Restart Router
- Share Your Public IP: Visit
whatismyip.comto find your public IP and share it with friends
⚠️ CGNAT Warning: If your ISP uses Carrier-Grade NAT (CGNAT), port forwarding won't work. Use Virtual LAN methods instead or services like Playit.gg.
Solution 4: Enable UPnP
Universal Plug and Play can automatically configure ports for Hytale.
Router UPnP:
- Access your router settings (see port forwarding guide above)
- Find "UPnP" settings (often under Advanced or Network)
- Enable UPnP
- Save and restart router
Note: UPnP may not work with all ISPs or router configurations. Virtual LAN is more reliable.
Other Common Issues
Multiplayer Not Working After Update
Solution: Ensure all players are on the same game version. Early Access updates frequently; check for updates in your launcher.
High Ping / Lag
Solutions:
- Close bandwidth-heavy applications (streaming, downloads)
- Use wired connection instead of WiFi
- Server host should close unnecessary programs
- Reduce server player limit if experiencing lag
Server Shows "Offline" Even Though It's Running
Solutions:
- Check that server console shows "Server started on port 5520"
- Verify firewall isn't blocking the server
- Restart the Hytale server application
- Ensure you're using Direct Connect, not the server browser (which may not list private servers)
Connection Times Out
Solutions:
- Verify the IP address is correct (common typo issue)
- Ensure port number is included (
IP:5520) - Check that server hasn't crashed (look at server console)
- Try pinging the IP from command prompt to test connectivity
