@bonienl can do that later for now i need to finish my work.
But until now about 6 friends had the same problem, and a couple ppl on the unofficial unraid discord also.
After update on 6.12 app store and dockerhub version information stopped working.
I checked the usual suspects and found out that my server time was stuck at 2002.
I'm using ntp with the pool: pool.ntp.org
I disabled ntp and enabled it again, without a change.
I rebooted the server without a change.
I changed the ntp address to plain ipv4 addresses instead of dns without a change.
[Temporary solution]
Only manualy syncing ntp on the command line with the command "ntpdate -u pool.ntp.org" seem to fix the issue:
root@unraid:~# ntpdate -u pool.ntp.org
17 Jun 17:38:56 ntpdate[29808]: step time server 94.16.114.254 offset +677166288.870671 sec
After a manual sync, all worked fine again.
So it seems the automatically syncing is broken anyhow.
I heard that problem from multiple people now in my bubble, and all had to manually sync to get the app store and docker versions back to work.
