No issue back then but now it could not connect to onedrive via iOS, no issue on windows or android.
Error message is “The operation couldn’t be completed. (MSALErrorDomain error -50000.)”
It occurred after msft login page completed.
Cloud service status showed onedrive has been already logged in.
I migrated my cryptomator safe from one MS365 tenant to another and therefore I needed to delete everything (safe and OneDrive credentials) in the app. After I logged into the new tenant account I got the MSAL error. The classic „login and logout“ approach didn’t work.
Deleting the cache and reinstalling the app didn’t work out either.
Here the solution:
Log into the old tenant account → Cryptomator Cloud Settings → OneDrive logoff → Delete App Connection/Permission in new tenant Azure AD → Log into the new tenant account at Cryptomator App → select safe
