Sync Task fails. failed - permission check failed. authentication failed - invalid ticket - expired

[eisteed]

Hi, I did set up proxmox backup server successfully at home and at a remote location for backup syncing.
Everything was working fine, sync successful.

Then I my internet connection has been stopped at home for 6 days for technical issues.
My IP has been changed since but other than that nothing else changed.

Now my sync task at remote site are failing only for two of my VMs

2022-05-20T14:19:44+02:00: TASK ERROR: sync failed with some errors.

Now I don't really know how to debug this, happened twice (sync every 24h).
I don't remember having to configure permissions

Thanks for any help
