Actual behavior

Hello, I just updated to the latest version of docker, and my container-xrdp has stopped working. The same goes for urdxp. These containers have been working for some years now. The error seems that xrdp cannot open or listen to the port inside docker. I was initially unsure where the error was originating from, so I created an issue in here since I thought it might be related to AF_VSOCK. The error seems to be a port binding failure.

Expected behavior

Port 33890 should be open and accessible via RDP.

I got the same error for PostgresQL on Docker: 4.17.0

The problem persists with 4.18.0 and Postgres, ad mentioned in #13229

I had the same issue with Postgres.

The problem in my case was I had the Postgres Server running on Windows.

Go to Service Management, and stop that service!

I hope that helps.

Port bindings on the host should not interfere with port bindings of containers.
