Can you please enable debug mode, reproduce the error and send us the log file or take a look into it.
A short time ago a user also had problems with mailbox.org and the cache. The server replied with a 412 HTTP status code. Please check the log if you find something like this:

If this is the case as a workaround you can disable in the Cryptomator settings the caching mechanism Settings — Cryptomator 1.7.0 documentation
