### :question: Game and server version don't match / cannot login

> [!NOTE]
> This is typically caused by a long-standing SteamCMD issue (affecting various games since 2015) where updates silently fail.
> Not specific to SCUM or this container.
> Check your logs for an entry like this: `Error! App '3792580' state is 0x6 after update job."`

**Workarounds that have helped others:**
- Restart the container multiple times until the update succeeds
- Delete `appmanifest_*.acf` files in `./scumserver-data/steamapps/` and retry forcing steamcmd to validate game files
- Last resort: back up `./scumserver-data/SCUM/Saved/`, wipe game files, let SteamCMD re-download fresh


## :information_source: Footnotes

Some port exposures are unnecessary. However, I could not find clear documentation which ports and protocols are actually required. Exposing additional ports/protocols won't cause harm.
