Invalid URL error for WebDAV sync

Hello,
I keep getting an error from Joplin on Windows. Somwhow it tries to construct an URL including a local path.
See this message:

Hi,
when does it happen ?

It happens after hitting the ‘Synchronize’ button in the left hand pane on Windows.
The status is ‘In Progress’ for a while, then I get the error.

ok,
may be there is a mistake in your webdav config in your joplin client. I’m not sure as I don’t use webdav for now.

Well, this may be. However, it worked in the past, and the setup is identical on Android where I don’t see this issue.
Any clue what I should check?

not me ; maybe some others users of webdav.
sorry :frowning:

if you downgrade of version ; does it work ?

Sorry, no. 1.0.103 gives me the same error message.
