Server won't start after patch today.

[BootieTrap]

Hi. I've been using the server without issues pretty much since you first made this. But today I'm having issue getting it started again after todays patch. I'm on Cachyos and it's all been working fine untill I decided to update cachyos today, rebooted and update the pull version to 1.6.2.

Here's what the log keeps looping pretty much

Hey, that is not good! Sad to hear that. I will try to help as much as I can. Just to be sure as it says, network is not working. Is it working correctly outside of docker?
windrose | [----] !!! Fatal Error: Steamcmd needs to be online to update. Please confirm your network connection and try again

Please do the following
docker stop windrose
docker run --rm --network container:windrose nicolaka/netshoot nslookup steamcmd.net
docker run --rm --dns 8.8.8.8 alpine nslookup steamcmd.net

cat /etc/resolv.conf
nslookup steamcmd.net
docker info | grep -i dns

provide raw output from SSH

thanks

how do I get raw output from ssh?

[UberDudePL]

@BootieTrap what you pasted is enough.
Good news — this is fixable! I can see exactly what is wrong from your output.

Problem 1 — DNS: Your host uses 127.0.0.53 (systemd-resolved stub) as DNS. Docker containers cannot reach that loopback address, so SteamCMD cannot resolve any hostnames. Notice that docker run --dns 8.8.8.8 alpine worked fine — it just needs an explicit DNS server.
First let's try quick fix:

sudo systemctl restart systemd-resolved

Problem 2 — wine: socket : Function not implemented: This is an AF_ALG socket blocked by seccomp — likely your CachyOS kernel update tightened Docker's seccomp profile. Add this to the same service block in docker-compose.yml

    security_opt:
      - seccomp=unconfined

after those two changes run

sudo docker compose down && sudo docker compose up

let me know what logs show after that

[BootieTrap]

It started the server and I think it works! Too much to show copy paste to show log.

Thank you so much!
