Have you used it with a different Nabu Casa account?
It will be held for 90 days after that account was deleted, or after the alias was disabled, for security reasons. It is recommended to use a different CNAME until that time (or just a different CNAME in general, there's an unlimited number you could use)
i got past that, but my custom domain gives a 404 error, the remote address works fine and i can login, but my domain gives a 404
@iron silo
i went with myhome.papalpenguin.com
did you restart ha after validating it?
it takes a minute or so for your ha server to request and download the certificate for the alias
you might want to delete the domain you are mentioning here
delete and re-add your server in the app?
uninstall or clear data for it
already tried clearing cache and then data no change, should i try uninstalling
there's no issue with the cert, it's whatever data the app or device is holding on to
or use your nabu casa url in the app
uninstalling and reinstalling same problem
interesting the casa url worked but my domain didnt
@iron silo
The Android app is rejecting https://myhome.papalpenguin.com because the TLS certificate being presented is for a different hostname: your screenshot shows the certificate “Issued To” is lb9ckdtvjqeb62izgmxbsxg7nupiboso.ui.nabu.casa, not myhome.papalpenguin.com. A browser can appear “fine” if you’re being redirected/forwarded to the .ui.nabu.casa address, but the app does strict hostname validation and fails when the cert name doesn’t match the URL you entered.
Any chance this might be the reason
Check the certificate details at Settings > Home Assistant Cloud > Security Options > More details

the screenshot was from my browser
@iron silo it looks like two different certificates
do I need to get a seperate cert for my domain
hmm using my domain via browser on my pc, home assistant keeps not wanting to connect
hmm if you have any ideas, ill just use the nuba.casa link for now
what you're seeing is correct. You might try restarting your router?
yeah i can try that
