🔧 Troubleshooting

Server Not Appearing in Browser

Issue: Server not visible in the in-game server browser.

Solutions:

Verify UDP port 27015 is open in firewall
Ensure sv_lan 0 is set (not LAN-only mode)
Check Steam master server is reachable
Try direct connect using IP:PORT to verify server is running
Validate game files via SteamCMD if corrupted

Connection Issues

Issue: Players cannot connect or timeout.

Solutions:

Verify firewall allows traffic on game port
Check server is not full (maxplayers limit)
Disable password if testing: sv_password ""
Check sv_pure settings if custom content conflicts
Review server logs in dod/logs/

High Ping/Lag Issues

Issue: Players experiencing high latency.

Solutions:

Set sv_maxrate 0 for unlimited bandwidth
Increase tickrate if CPU can handle it: -tickrate 100
Set fps_max 600 or higher
Check server CPU usage (should be under 70%)
Verify network bandwidth is sufficient for player count

RCON Not Working

Issue: Cannot connect via RCON.

Solutions:

Verify rcon_password is set in server.cfg
Ensure TCP port (same as game port) is open
Use Source-compatible RCON tools
Test RCON from in-game console first

Server Crashes on Startup

Issue: Dedicated server crashes immediately.

Solutions:

Check dod/logs/ for error messages
Validate game files: steamcmd +app_update 232290 validate +quit
Ensure server.cfg syntax is correct
Remove plugins temporarily (SourceMod/Metamod)
On Linux, install required 32-bit libraries

SourceMod/Metamod Issues

Issue: Plugins not loading or causing crashes.

Solutions:

Ensure Metamod:Source is installed before SourceMod
Verify plugin compatibility with DoD:S
Check addons/sourcemod/logs/ for errors
Update SourceMod and Metamod to latest stable versions
