Those are my files which should run my application on an HTTPS connection. I have an index.html file which I added manually and the rules I added manually which does work. But when I try to run my webapp on these settings it doesn’t work. When I go to my url with the port it says SSL PROTOCOL ERROR. Am I missing out on something?

I’ve been trying to get this work for the past 2-3 days. The HTTP did work before but I changed my nginx.conf to try and make it work with HTTPS but no success so far. I would appreciate any help!
