Cannot sync with webdav on computer but sync is okay on app android

guillaumebouzige
When i try to sync on my computer I have an error message so when i go in setting to click on 'verify server' I receive this error :

Permission denied
The WebDAV server did not accept the username and password you entered.
Please check your file sync settings or contact your WebDAV server administrator.

but with that same server, same credential on android App I can confirm the server is okay.

I have contacted the administrator of my webdav server that confirm to me that my account and the server has no issue, the password is correct and the server webdav is working.

How can i do to sync my zotero on my computer ?

Thanks

    If you provide a Debug ID and we can take a look (your password isn't logged), but that error really means what it says.

    Can you provide the output for these from this machine?

    curl -i -X OPTIONS [WebDAV URL]
    curl -i -u [username] -X OPTIONS [WebDAV URL]
