Investigation in progress - SteamCMD-based servers
We have identified an issue affecting some game servers that rely on SteamCMD (DayZ, ARK, Palworld, Arma Reforger, 7 Days to Die, Source games, and other Steam-distributed titles).
Affected servers may display the following error on startup:
```
Fatal Error: Steamcmd needs to be online to update.
Please confirm your network connection and try again.
```
Root cause
The recent mitigation for CVE-2026-31431 (CopyFail) has resulted in a tightening of Docker's default seccomp profile (versions 29.4.2 and later). This tightening blocks the 32-bit socketcall syscall, which is used by the SteamCMD bootstrap process as well as some Wine-based applications. Network connectivity is not the cause; the issue lies entirely within the container isolation layer.
Ongoing action
Our team is rolling out an adjusted seccomp profile on the affected nodes to restore SteamCMD functionality while keeping CopyFail protections in place (patched kernels). No action is required from you; your servers will restart automatically once the fix is applied.
We will publish an update as soon as the rollout is complete. Thank you for your patience.
