Docker I am encountering the error [Errno -2] Name or service not known

I am encountering the error [Errno -2] Name or service not known when I attempt to start the server on Docker. Below is a snippet of the log error:
fief run-server --host 0.0.0.0:8080

Log:

I have verified the network connectivity between the Postgers, Redis, Server, and Worker servers. All servers are on the same network and can ping each other by name and IP address without any issues.

I am unsure if there is a way to start the server in verbose or debug mode to gain a better understanding of the error. Any suggestions on how to approach this would be greatly appreciated.

Not sure it comes from there but the --host option doesn't support the port. The correct syntax is --host 0.0.0.0 (which is actually the default). To specify the port, all you need is to set the PORT environment variable.

Thank @frankie567,

I suspect I made some confusion with the many attempts I made to get the server running.

I removed the door, and now I am able to connect to the server.

Thanks for your help.
