Hey @not-alone, sorry to hear you're experiencing issues.

Could you try the following in this order, please? This looks like a game bug, but I'd like to rule out the container first:

• Remove the :/config volume mount completely, this will rule out various potential issues
• Try image version v1.8.10, this will verify Ubuntu 24.04 (/kernel) isn't the issue
• Try image version v1.7.4, this will verify Ubuntu 22.04 (/kernel) isn't the issue

Thanks!

[not-alone]

Good day, @wolveix, thank u for really fast answer!!!

• removing volumes chapter at all is not helps
• image version v1.8.10 working like a charm without any problems
• image version v1.7.4 working too without problems

[wolveix]

Hey @not-alone, that's very interesting! Other people have had somewhat similar issues over the years. Unfortunately they're incredibly hard to pin down. Which version of Ubuntu are you running on your host, out of curiosity? I suspect upgrading your kernel may fix the issue

There is no available updates for kernel :(

[wolveix]

Hey @not-alone, see this: https://www.omgubuntu.co.uk/2024/01/ubuntu-2204-linux-6-5-kernel-update.

To be clear, I'm not saying it'll resolve the issue for certain. It could be your version of Docker, your kernel, or 101 other things. If you're willing to try upgrading your kernel (Ubuntu usually makes the process pretty seamless), please do

[not-alone]

i did kernel update to Linux xxx.biz 6.8.0-52-generic #53~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jan 15 19:18:46 UTC 2 x86_64 x86_64 x86_64 GNU/Linux.
No result

[wolveix]

@not-alone I just remembered that we reverted the Ubuntu 24.04 rebase with v1.9.1, so that's not the issue. Could you try setting -e MULTIHOME=""?

[not-alone]

not working too :(

[wolveix]

And just to double check, setting MULTIHOME="" removed the Setting mutlihome line towards the start of your contianer log, right?

• MULTIHOME="" seems not work

[wolveix]

As you're using a Compose file, try setting it to nothing, e.g. MULTIHOME=

[not-alone]

YEAHHH!!! it works with

cat docker-compose.yaml
services:
  satisfactory-server:
    container_name: 'satisfactory-server'
    hostname: 'satisfactory-server'
#    image: 'wolveix/satisfactory-server:v1.8.10'
    image: 'wolveix/satisfactory-server:latest'
    ports:
      - '7777:7777/udp'
      - '7777:7777/tcp'
    volumes:
      - './config:/config'
    environment:
      - MAXPLAYERS=4
      - PGID=1000
      - PUID=1000
      - STEAMBETA=false
#      - VMOVERRIDE=true
#      - DEBUG=true
      - MULTIHOME=
    restart: unless-stopped
    deploy:
      resources:
        limits:
          memory: 10G
        reservations:
          memory: 8G

[not-alone]

@wolveix should i provide any additional information to completly identify the root of the problem?

[wolveix]

Fascinating, so it breaks if MULTIHOME is set at all huh :D Satisfactory is always a fun one.

I'll think about how we should handle this. Thanks for testing it out! Would you mind sending the output of this? Probably irrelevant, just curious :)
