Hello, I'm pretty new to this so forgive me if this is a basic question. I have successfully managed to setup SWAG and got emby working on it, now I'm trying to do the same with Nextcloud. When I installed this container it didn't map any ports for me so I created a new HTTP mapping (80 to 8080) and I did the same with HTTPS (443 to 4443). It works and installs fine on port 8080 but it does not answer at all on port 4443. In the official image of nextcloud I can see that only port 80 is exposed (https://hub.docker.com/_/nextcloud) but if this is the case then how can I setup SSL for it? I tried changing stuff in nextcloud/config/config.php (trusted domains) but no matter what I did it wouldn't work. I would appreciate any help. Thank you
