Hello Flarum Community,
I need some assistance with an SSL issue on my Flarum forum. I followed this guide (https://www.vultr.com/docs/how-to-install-flarum-forum-on-ubuntu-20-04/) to set up Flarum on Ubuntu 20.04, and everything was fine until I installed an SSL certificate for my subdomain (flarum.domain.com).
Here's the problem:
HTTP Works: The forum works perfectly over HTTP (http://flarum.domain.com).
HTTPS Error: After installing the SSL certificate, I'm getting an SSL error when trying to access the forum over HTTPS (https://flarum.domain.com).
Cloudflare: I use Cloudflare for DNS management. The main domain (domain.com) works with SSL hosted on other server, but the subdomain's (flarum.domain.com) SSL isn't functioning as expected.
I've tried various solutions, but nothing seems to work. If anyone has encountered this and has a fix, I'd appreciate your help.
