### Steps to reproduce

Try to upload multiple folders with music in them (~a few hundred files total) from a folder called music on a mobile device to a similar folder on the nextcloud server hosted on the local network.
Also, of note the app said I had no internet connection although I do (I'm posting this on the same device, right after the error).

### Expected behaviour

Upload files successfully without errors.

### Actual behaviour

Crash with a huge unhandled exception. Fuzz testing is needed.
