The reply by @jackw.27 got me thinking it is all a network a problem; I had some UniFi firmware upgrades recently and an update to the Controller. But that didn’t make sense to me as it was only affecting HA and @NickRP7 described a gradual ‘degradation’ which I think I also experienced with my wall tablet going first.
So for some reason I decided to just try one more time before some taking some radical action. I used Incognito mode on Chrome on my tablet and Lo! it worked. Then I went back to Fully Kiosk, tried that and yes, it works now too!
I can categorically say nothing has changed since posting yesterday except for a few restarts of HA.
I know you won’t believe me
So I’m happy it appears to be all working now but not happy that I don’t know why it is, or why it stopped working in the first place.
I’ll be keeping a nervous eye on things.
I do wonder if there is some underlying issue because I have discovered this is not the only current thread regarding being stuck on ‘Loading Data’.
I’ve found a way to solve it…
Open “auth” file in /config/.storage/ and under “refresh_tokens” remove all token with access_token_expiration: 1800.0 (everything exept the long term tokens)
After a reboot “loading data” disappeared permitting me to login in with username and password.
It seems that the token expiration has something to do with this…
Ah… this might make some kind of sense.
I never log out. Maybe that has something to do with it?
Maybe they are expiring while still logged on?
And on my FK tablet I sometimes tell it to reload the start URL which maybe requires a login?
I might be clutching at straws here because I know that doesn’t sound like that is the way it should be but………
At the risk of committing necromancy, I have this issue aswell.
Frontend seemingl randomly stops responsing (Loading Data…)
Existing logged in browsers seem to be able to keep interacting with HA, but they eventually run across some reason to refresh and then the spinning wheel of doom hits them too.
Several hours later, it seems to sort itself out. Both occurrence and fix happen without restart or intervention that i’m aware of, and I’ve not been able to find a common trigger yet.
Already tried:
Deleting the .storage directory
Deleting auth file
Deleting tokens in auth file
Reverting to a previous snapshot
I’ve just run into this same issue, but it only happens when I upgrade to .108.x. It runs fine on .107.7. I’m running HassIO on the Raspberry Pi 4. I haven’t let it sit for longer than 15 minutes. Maybe I’ll try that?
Today this happened to me so i slowly removed items i added in previously, and found that sensors.yaml will not handle letter Ä that was on there. removed that and it solved itself immdiately!
