Failed to login to SSH session - Ubuntu (not WSL)

[cian0]

          I have a fresh install with docker, I'm getting the same error below

my command:

docker run -it \
    --pull=always \
    -e LLM_API_KEY \
    -e LLM_MODEL \
    -e SANDBOX_USER_ID=$(id -u) \
    -e WORKSPACE_MOUNT_PATH=$WORKSPACE_BASE \
    -v $WORKSPACE_BASE:/opt/workspace_base \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -p 3000:3000 \
    --add-host host.docker.internal:host-gateway \
    --name opendevin-app-$(date +%Y%m%d%H%M%S) \
    ghcr.io/opendevin/opendevin

The error:

Could you check if the sandbox container is running in Docker Desktop and log in using ssh -v -p 34161 opendevin@localhost if so?

Same issue in NixOS. I can log into the opendevin-sandbox container using ssh from the host but not from inside the opendevin-app container.

[SmartManoj]

Could you please provide the logs?

This was a firewall issue. I resolved this by adding docker0 to networking.firewalls.trustedInterfaces. @cian0 Claude tells me sudo ufw allow in on docker0 and sudo ufw reload is the ubuntu equivalent to this.

I can confirm this solution works on my server as well. Thank you!

This worked for me too, thanks for the hint. I used IPTABLES to fix this.
