Description

I use the liveserver fixture with a fixed port because I need SSL and have nginx setup in front of it. The first test runs fine, but when running another pytest session before TIME_WAIT expires I get the address already in use error. I suspect either cleanup is not done properly when the liveserver quits or it's just a TCP/IP thing.

Is there a workaround for this? I really need the fixed port because otherwise proxying from nginx won't work.

Thanks!

Research direction

Start by reproducing the fixed-port liveserver failure across two pytest sessions, then inspect the liveserver fixture's shutdown and port cleanup behavior. Done means the second session can run before TIME_WAIT expires, or the issue documents a verified workaround for fixed-port SSL setups.
