Open port 4001 for https on ubuntu VPS

@grf

Really all I need to do is find a way to make the requests to port 4001 over https to reach that app that is running on localhost:4001

1. Can you explain why this needs to happen.

Yes, this can be done but requires way more work than just serving it over 443

2. Also - will your 80 and 443 be open on this VPS?
