Portfinder (used in serve/e2e) is not finding an open port on Windows

[isayneigh]

Expected behavior

Be able to have skyux serve running and run skyux e2e in a separate terminal.

Actual behavior

If I run skyux serve and leave it running, then run skyux e2e, skyux e2e hangs indefinitely. Cancelling skyux serve allows it to continue.

Steps to reproduce

• Run skyux serve
• run skyux e2e
• e2e should never complete

Hey @blackbaud-joshlandi Do you see the same behavior with running skyux serve at the same time in Windows?

[blackbaud-joshlandi]

Yeah, this is in Windows 7. I haven't checked it in other OS'

[Blackbaud-BobbyEarl]

I realize you're specifically testing using serve in conjunction with e2e. Since you're on Windows, do you mind testing serving two spas at the same time and see if you get an error?

[blackbaud-joshlandi]

served two of the same spa and got this error:

Fails on Windows 10 too.
