I created a little multiplayer game to learn how Python's asyncio worked. I tested everything on localhost first -- everything worked. I then used ngrok to expose my localhost so I could play with some friends. However, every time they connected through ngrok, their client never updated. The client would send messages through the web socket, but it wouldn't receive anything. For a long time, I thought it was a bug in my code. Then, I tried using localtunnel instead of ngrok, and to my surprise, it worked as if it were just localhost again.
So my question is: what differences are there between localtunnel and ngrok that allowed the web socket communication to work properly in localtunnel?
