OS Name/Version: Fedora 41: Kernel 6.12.5-200.fc41.x86_64
Product Name/Version: AMP 2.6.0.12 - 20250224.1
Problem Description: Can’t connect to fresh instance of DayZ (stable) on LAN
Steps to reproduce:
- Created new DayZ stable in existing AMP server
- Minimal configuration tweaks performed via UI (server name, desc, etc)
- Started server, reviewed console logs, confirmed it appeared running
- Tried to “direct connect” to LAN IP Address and game port shown on status page via the DayZ (stable) launcher. It silently fails.
- Clicked on the Steam Query Port link on the status page. Steam tried to connect and returned with a “Invalid App Id” msg
- Noted that the server doesn’t show up in the launchers LAN tab
Actions taken to resolve so far:
Several hours troubleshooting. See below foe details
Some details from my troubleshooting:
- The DayZ container is using the host network mode.
- The ports are listening on the host machine (as confirmed by ss).
- No connection attempts are recorded in the DayZ server logs.
- I play DayZ on public servers daily from my desktop using these standard ports so they shouldnt be blocked on the client side.
atlas ~ $ docker ps -a
