[Bug]: Check Connection fails with status 415, but sync works

[MarkLodato]

Real Outcome

In the Settings page, clicking the Check Connection icon fails with error:

Check connection failed: Request failed, status 415

However, syncing works fine.

This happens for me on both Windows and iOS. I am using the WebDAV backend.

Expected Outcome

Check Connection would succeed.

Backend

lighttpd mod_webdav over local network

Steps to Reproduce

1. Go to Settings.
2. Enter WebDAV configuration.
3. Click Check Settings. The error pops up.
4. Exit settings and click Start Sync. It works.

Support Log

There does not seem to be any log related to the Check Connection, but here are the logs that I have. I have redacted the exact filenames since they are not relevant to this bug.
