Jitsi Meet Quick install Guide shows Nginx welcome

Hi everyone,

I tried to install Jitsi Meet on a Digital Ocean droplet.
I Followed the Quick Install Guide step by step and everything executes smoothly.
Nonetheless, once I am finished and I go to my domain in a Webbrowser I see a Nginx welcome Page.
I figured out its http only, once I connect to https I get the Jitsi Meet interface.
Nonetheless I have two more issues. First of all, I can join the conference but I don’t see other participants and also I can’t activate my camera for example.
Secondly my proxied cloudflase connection (which ensures secure ssl certificate) doesn’t work.

Has anyone had similar issues beforehand?

Greetings,
Jan
