We’ve been working on localhost so much that I think I forgot to ever tell you guys how to get your Flask app running on the actual internet on the cpsc server. Duh.

The answer is, when you start Flask, do it this way:

$ flask run -h 0.0.0.0 -p yourPortNumber

The 0.0.0.0 is literal. The yourPortNumber” should be replaced with your port number.
