Hello again. I have attached log file with a failed attempt. Then I tried to set ignore_dav_header and mount was successful this time.

My WebDAV server is based on Nginx http_dav_module with an extra module After digging into the issue I realised that my server returns HTTP Header "DAV: 2" while it should be returning "DAV: 1, 2". A small change in my Nginx config seems to have solved the problem.

Message "the server does not support WebDAV" means that the server does not send a proper DAV-header in response to OPTIONS. You canwork around this server bug by setting option "ignore_dav_header" in your davfs2.conf file.

But you also should help to debug this problem. To do this

  • set option "debug most" (without option ignore_dav_header)
  • try to mount
  • when mounting fails get the messages from mount.davfs from one of your log files and append them to this request
  • remove option "debug most"

I will examine the logs to check what the cause of this error is so you can eventually inform the server administrator.

Password-protected WebDAV share fails to mount with the following error: /sbin/mount.davfs: mounting failed; the server does not support WebDAV

During the mount attempt, only two requests are sent to WebDAV server: - - [06/Jul/2020:05:04:03 +0000] "OPTIONS /bookmarks/ HTTP/1.1" 401 172 "-" "davfs2/1.5.4 neon/0.30.2" - myshareuser [06/Jul/2020:05:04:03 +0000] "OPTIONS /bookmarks/ HTTP/1.1" 200 0 "-" "davfs2/1.5.4 neon/0.30.2"

The very share works perfectly with the default macOS client.
