Gateway Timeout issue

[mregni]

Thanks for the fast entrypoint fix!

I tried your new solution and it seems to be working (config in traefik looks good) but I always get a Gateway Timeout when I call a service on my sub machine.

sub traefik dashboard

I'm not sure what is happening. I can see a gateway timeout on my main machine but nothing on my sub machine meaning the call to 192.168.72.225:80 is failing. Any idea why?

Ow, if I navigate to the whoami service directly, there is no issue. So it's not the docker service itself. Maybe I'm doing something wrong with the setup between the main and sub machine?

Thanks for the great work already!

Nevermind, I'm so stupid My sub machine IP is 192.168.72.225 instead of 192.168.72.255 (wrong config)

Haha that's fine. Enjoy your working config now!
