Help with port closed

At some point I had NC working fine and then I played around with encryption and broke it.

Long story short I re installed NC from scratch.

I have it setup on an external drive on Windows 11 using Docker

Although I had already opened the port 443 on my router previously and I checked again that it is still open, when I test on portchecker it shows CLOSED.

Docker doesn’t show me any errors

I am able to get to https://localhost:8080/containers

when I enter the URL it gives the error:
Domain does not point to this server or the reverse proxy is not configured correctly. See the mastercontainer logs for more details. (‘sudo docker logs -f nextcloud-aio-mastercontainer’) If you should be using Cloudflare, make sure to disable the Cloudflare Proxy feature as it might block the domain validation. Same for any other firewall or service that blocks unencrypted access on port 443

Any help?

Maybe the domain is not set up correctly anymore os that it does not point towards your public ip-address anymore?

How can I verify all of that?

I did check my firewall as well and I think it is ok.

The domain is setup through
