As of today, I have the problem that the computer from which I access my Home Assistant Server no longer has proper authentication. I can access the regular HA points, but all addons can no longer be viewed.
As if I no longer have access rights to myself. I am logged in as the owner.
First of all, yes I go in with http://. But I tried to set up Alexa a few days ago and, among other things, communication via https:// was a requirement. I realized this using the duckdns addon.
In the end it didn’t go right and I drove everything back. Apparently there is something stored somewhere in FireFox that declares these pages to be unsafe, or there is information stored in the HA that says that these pages are denied to me as user xy.
I managed it. Whatever way I managed to lock myself out of FireFox.
I deleted all history and data in FireFox that were primarily related to HA. Then I closed FireFox.
I then went to my user profile with Microsoft Edge and clicked on Security. Here you can see all the tokens that were created. Sessions, I would say. I deleted all the tokens except the one that had a green marker, since I was in with Edge.
I then restarted FireFox. And a new token was created. And lo and behold, I can now access all the add-on interfaces again without this error message.
I was so frustrated that I almost considered reinstalling HA.^^
With that in mind, if anyone happens to have the same problem, I hope this will help them.
