The Front Server Troubleshooting Guide

Common issues with The Front dedicated servers and how to fix them. Follow these solutions before contacting support.

🔧 Quick Checks First

  • Check ports are forwarded (7777, 27015, 27016)
  • Review logs for error messages
  • Restart server and clients

Connection Issues

Connection Failed

Symptoms: Players cannot join, timeout errors

Causes:

  • Port forwarding incorrect or missing
  • Firewall blocking connections
  • Server version mismatch
  • IP address changed

Solutions:

  1. Verify port forwarding: UDP 7777, 27015, 27016
  2. Check firewall: sudo ufw status on Linux
  3. Update server to latest version
  4. Confirm correct IP in config

Server Not Showing in Browser

Symptoms: Server exists but invisible to players

Solutions:

  1. Check QueryPort in GameUserSettings.ini (default 27015)
  2. Verify query port forwarded: UDP 27015
  3. Check Steam master server connection
  4. Restart server after config changes

Performance Issues

Server Lag

Symptoms: Rubber-banding, delayed actions, low FPS on clients

Causes:

  • Insufficient CPU/RAM
  • High player count for hardware
  • Complex bases and structures
  • Network latency

Solutions:

  1. Upgrade hardware resources
  2. Reduce max player count in config
  3. Increase tick rate for smoother play
  4. Optimize network settings

Frequent Crashes

Symptoms: Server shuts down unexpectedly

Solutions:

  1. Check logs: TheFront/Saved/Logs/
  2. Verify all config files are valid

  4. Check disk space (need at least 50GB free)
  5. Reduce max players if resource exhaustion

Startup Issues

Server Won't Start

Causes:

  • Missing dependencies
  • Corrupt server files
  • Port already in use
  • Invalid configuration

Solutions:

  1. Reinstall server from SteamCMD
  2. Check ports aren't blocked: netstat -an | grep 7777
  3. Validate config file syntax
  4. Run server with -log flag for diagnostics

Authentication Errors

Symptoms: "Authentication Failed" when connecting

Solutions:

  1. Verify Steam is running on client
  2. Check server password in config
  3. Restart Steam client
  4. Check Steam server status

Configuration Issues

Settings Not Applying

Solutions:
