WebDav Fails, Works From Finder/Explorer

I’m struggling with WebDav from Joplin. My WebDAV server works for Findor (Mac) and Explorer (Windows) access at https://mydomain/dav/joplin/

By “work”, I mean I can map/mount a drive at that URL and see the files which are there.

But when I tell Joplin it should sync to the same URL for WebDAV and provide the same ID/password, I get a 401 status. I’m using AuthType Digest. Is that a problem for Joplin? What else should I look at?

Update: Yeah, it sends Basic auth. I connected it to a DAV repository which uses Basic and it connected right up.
