VEIN Dedicated Server Troubleshooting
Start with the smallest reproducible symptom. VEIN has main and experimental branches, and community configuration examples do not always match the current build.
Triage table
| Symptom | First checks |
|---|---|
| Server process exits | Binary/package, branch, working directory, dependencies, and log. |
| Not listed | Process ready, query UDP 7778, listing state, and provider mapping. |
| Listed but cannot join | Game UDP 7777, firewall/NAT, password, and client/server build. |
| Settings ignored | Active instance, section/key support, panel overwrite, permissions, and clean restart. |
| World is wrong or missing | Active save path, clean stop, backup, and package/world selection. |
| Everyone lags | CPU, memory, disk, save activity, logs, and recent build change. |
| One player lags | Client performance, route, VPN/firewall, and local build. |
Collect evidence
- App, branch, build, OS, and provider template
- Exact error and timestamp
- Whether all players reproduce it
- Relevant log lines and resource use
- Whether a fresh world changes the result
Safe recovery order
- Stop changing unrelated settings.
- Back up the world and current files.
- Reproduce on a test copy.
- Change one variable.
- Restart and retest.
