WebDAV verification failed

Hello all,

When I click sync button it synchronizes correctly, but the sync button turns to red and gives the following error:

"WebDAV verification failed. Verify your file sync settings in the Sync
pane of the Zotero preferences."

I have checked on the server side and mobile app if files synchronized correctly; yes, all files are synchronized. Just sync now button turns to red.

It also gives following error message when I click verify server button sync settings in the Sync pane:

"Error
An unknown error occurred.
Please check your file sync settings or contact your WebDAV server administrator.
HTTP 400"

I am able to connect to WebDAV server page without error in chrome

Please help to correct. Thank you

    It also gives following error in "error console"":

    [JavaScript Error: "XML Parsing Error: not well-formed
    Location: https://insanbil:*****@insanbilimleri.com:2078/zotero/
    Line Number 1, Column 1:" {file: "https://insanbil:****@insanbilimleri.com:2078/zotero/" line: 1 column: 1 source: ""}]
  • Can you provide a Debug ID for a Verify Server attempt that fails?

    If Verify Server fails, it shouldn't actually sync any files, so I'm not sure how you'd be seeing files elsewhere unless you synced those previously.
  • Sorry, you are right, there is no new files synchronized.
    But I have had tested via a "child note". It has been synchronized both way.

    Here is debug ID: D245537687

    I have also reported the error. Report ID: 1566032073

    Thank you very much for your concern
  • Notes don't have anything to do with file syncing.
    HTTP PROPFIND https://[…]@[…].com:2078/zotero/ failed with status code 400:
    It's just a 400 Bad Request error from your WebDAV server. That's all we can tell you. It's not a problem in Zotero itself.
  • I have checked from WebDAV server side with server admin. He found no problem.

    I have also provide debug and report Id's and submit error log via zotero.

    Thank you

    Zotero works with properly configured WebDAV servers. Your WebDAV admin will need to look at the server logs and determine why the server is returning a 400 for a valid PROPFIND request.

    The server is also returning invalid characters as the response text, which a properly behaving server wouldn't do, so we can't even tell you what the server claims is the problem.
