Fail to upload files to yandex drive vault

Hi. I’ve created a vault in yandex drive through WebDAV connection. The connection is on and there is no problem with it. But when i try to upload files to the vault, the progress is stalled at copying the 1st file to the vault.
I tried it on another mobile phone with no success. Any idea how to workaround the problem?

Hey and welcome to the Cryptomator Community :slightly_smiling_face:,

Can you please enable debug mode, reproduce the problem and send us the log file? How do I enable debug mode on Android?

That should help to find out what’s the problem.
