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?

I’m having the exact same problem. Chrome, mobile, android app all works, but Firefox does not.

I’m running Firefox 110.0 on Fedora.

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.

You’ll need to reset your Firefox to Default settings:

  • On Windows you can do this by clicking the three horizontal dash marks in the upper right corner (underneath the “Close” button).
  • Click “Help”
  • Click “More Troubleshooting…”
  • Click “Refresh Firefox” underneath ‘Give Firefox a tune up’

Let Firefox cycle, reopen Firefox and log into your local instance of Home Assistant. Done

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.

Anybody work this out? I have tried all of these and more

In my case the reply above yours fixed my issue. I didn’t realize firefox defaulted to not using my router’s DNS, which uses the exact same DNS over HTTPS/SSL, but my dns server has DNS overrides for my external domain name to set the IP to the local ip rather than my external one, reversing hairpins and keeping it on the same local switch.

Turn off DNS over HTTPS! and move that functionality to your home router

Can confirm that this worked for me. Went into Firefox settings and added my internal DNS name for my home assistant to the DNS over HTTPS exclusion list and it started working right away.

Thanks!
