Hytale Server Troubleshooting Guide

Here are common Hytale server issues and how to fix them.

Failed to Connect to Server

Common error messages:

• "Failed to Connect to Server. The host may be offline or behind a strict firewall"
• "Could not connect to any available address"
• "An unexpected error occurred"
• I18nModule.getMessages (I18nModule.java:315)

Change Your System Language (I18nModule Fix)

The most common cause of the I18nModule.getMessages error is a language or locale mismatch on your system.

Disable Your Firewall

If the error mentions "strict firewall," your Windows Firewall or antivirus might be blocking the connection.

1. 1
   Search for Windows Defender Firewall in the Start menu.
2. 2
   Click Turn Windows Defender Firewall on or off.
3. 3
   Select Turn off Windows Defender Firewall for both Private and Public networks.
4. 4
   Try connecting to the server again.

If this fixes the issue, add Hytale as an exception rather than leaving your firewall disabled:

1. 1
   Go back to Windows Defender Firewall.
2. 2
   Click Allow an app through firewall.
3. 3
   Click Allow another app and browse to your Hytale installation.
4. 4
   Make sure both Private and Public are checked.
5. 5
   Turn your firewall back on.

Sync Your System Clock

An incorrect system time can cause authentication failures when connecting to servers.

Check Your IP Address and Port

Double-check you're using the correct connection details:

• Confirm the IP address with the server host
• Include the port number if it's not the default
• Check for any typos

Verify the Server Is Online

Before troubleshooting further, make sure the server is actually running:

• Check Bropanel to verify it's online
• Check for error messages in the server console

Slow Connection / World Not Loading

Symptoms:

• Your internet is stable (YouTube works fine)
• Singleplayer loads normally
• Server connection is very slow or world won't load
• Friends can see you move but you can't do anything
• You're on Windows

Cause: Some Intel & Realtek network drivers have issues with QUIC, the modern protocol Hytale uses. This affects both Wi-Fi and Ethernet.

Confirm the issue: Connect an Ethernet USB dongle. If that fixes it, follow the solutions below.
