Hello, I have the same problem. No connection is possible with Firefox (current version). Even from different PCs. With Chrome, Edge or Safari, access works without problems.
Does it seem to be the browser?
Another “same here”. It works fine with Chrome and Safari, just not Firefox.
I’ve tried “Forget about this site” and browser restarts. I’ve also emptied my dashboard because I’ve seen reports that “external” cards can create issues. No luck.

It has worked before, just not after the latest updates I feel. I am using the Duck DNS addon with Let’s Encrypt configured.
Edit: A third “Forget about this site” plus browser restart helped somehow.
Reseting to defaults does not helped me.
main bug is using dns-over-https. complete turn-of this feature and recheck. It is helped for me.
I think this approach will help you when your try to connect within local network using dns name (not ip).
but in my case this manupulation helped also for direct connectiton by ip. I don’t understand why.
