i use a yunohost selfhosted easy!appointments version, and recently upgraded. i really enjoy it, especally the fact that it syncs with caldav - although unfortunately it no longer seeems to sync at all post upgrade. i get (for one that was already synced pre-upgrade:) CalDAV Sync: CalDAV URL host is not allowed. and for one that i am trying to re-sync, a message that appears instantly saying "Login failed, please enter the correct credentials and try again.
Calendar synchronization failed: Could not establish server connection."
any ideas? i tried force upgrading both my nextcloud and easyapppointments apps, as well as rebooting the machine.
