Android unable to connect to WebDAV

jenbadham
I believe there is a known fragility with android devices syncing with WebDAV as I have found several other posts and checked the things mentioned in those.
- (not) digest
- credentials are the same on my android and computer WebDAV settings in zotero

Debug ID is D345328406

What works:
- WebDAV setup with CPanel Web Disk cPanel Web Disk, https://jbadham.biz:2078
- works with two different computers, i sync between home and work fine
- Generic android WebDAV client (Solid Explorer) is able to access the files in the zotero folder using the same credentials

What doesn't work:
- Android tablet (Samsung Galaxy Tab A9, Android 16)
- Zotero android app version 1.0.0-247
The error message is "Could not connect to WebDAV server"

I have tried with both the wifi network (that the home computer uses successfully) and my phone as hotspot. I also uninstalled/reinstalled zotero.

Any other ideas?

Thank you

    The server is broken. It's returning content for a 204 No Content response. From that page:

    "Note that the response must not include any content or the Content-Length header (browsers may reject responses that include content)."

    Then why does it work fine for my computer? I have no trouble syncing on that

    See what I quoted. HTTP clients could choose to ignore this, but it's a malformed response, and clients can reject it. The HTTP library we use in the Android app does.

    Okay. Thank you for your help, I will see if I can work out if there's any settings to fix that
