0 should be a supported port

1. 0 should be a supported port.
2. Yikes to this error message:

Error: Port should be >= 0 and < 65536. Received 0.

Hey, can you provide reproduction steps? Also, what version are you using?

[sewinter]

Hi David, I'm on 7.4.4. Repro:

 const server = ganache.server({
      fork: {
        url: FORK_URL,
      },
      server: {
        ws: true,
      },
    });
    server.listen(0);

Looks like a duplicate of #2643. I'll try to get the priority bumped up on this for you. I suspect it will be an easy fix. Thanks for reporting!

Thank you! I ended up writing a utility to find a free port, so it's not super urgent for me.
