How open HTTP traffic
If you are asking how to make an https server on Replit:
Replit automatically serves an https alternative to your normal http server, so you don't need to make an actual https server, just make a normal http server.
If you are asking how to get your server load at all:
It is loading, it just takes forever, which isn't really anything to do with your code, that's just a Replit problem.
Btw: about that image you have... ignore that message you already have all that just reload the webpage a couple times or wait a couple minutes and it should be up.
