I am trying to connect to my android smartphone my cryptomator folder from my personal nextcloud server and I get the error “Webdav could not be authenticated”.
I fill in username and password from nextcloud correctly.
The webdav url is https://mycloud.duckdns.org/remote.php/dav/files/user/
My server runs on ubuntu server 20.04, latest nextcloud version and the ssl is done using let’s encrypt.
If the URL provided by @Michael doesn’t work, you can check if you’ve enabled 2FA in Nextcloud. If so you must create a app password and use this one instead of the user password:
