Deployments stopped working. Hostingpid1: an open port was not detected

[rexhall]

Problem description: When I deploy python repls they fail promotion with the last thing being a Hostingpid1 message.

Expected behavior: I press deploy and python web server starts.

Actual behavior: I press deploy and promotion fails.

Steps to reproduce: I’m not sure if it is reproduceable, but I ha e tried making a blank python repl and creating a flask server with ghostwriter ti test, and that fails in the same way.

Browser:I hqve tried chrome and firefox, but I assume all.
OS:I have tested deployments on windows and android
All devices
All versions

Try to test to see if the site is up within 5 seconds, this was the issue with one of my repls. If not, see if there is an older version of the code that worked that you can revert to.
