Cannot login to vault; say file cannot be found

When logging into my Cryptomator vault I get this message to sign into Microsoft. The file I am using is on OneDrive and have never been asked to sign in before. I signed into M/S and set Cryptomator to access OneDrive. When entering password to enter my vault I get the message “” could not be found. Can anyone help me? I cannot access my vault on mobile. See attached picture:

Hi. Had the same issue a view month ago with OneDrive. Deleting the connection and adding it again solved the issue for me at the end. Never had the issue again since then.
See here what I did in detail: Error "/" could not be found - #8 by Michael
