rclone critical failed dav files user endpoint dav/files/username

Rclone critical failures at /dav/files/username usually stem from outdated WebDAV endpoints, specifically when using Nextcloud. Modern rclone requires the precise endpoint https://example.com instead of /webdav to support chunked uploads. [1, 2]

Steps to Fix:

Correct the URL: Update your rclone config to use https://your-server.com.Verify Vendor: Ensure vendor = nextcloud is set in the configuration.
Use Proper Credentials: Ensure the password provided is a valid app password (especially if 2FA is enabled).Trailing Slash: Verify the URL ends with a trailing slash (/). [1, 2, 3, 4]

Example Config (rclone config):

ini
[nextcloud]
type = webdav
url = https://your-server.com/remote.php/dav/files/username/
vendor = nextcloud
user = username
pass = password 

If issues persist, use
rclone -vv
to check logs, as 404 errors indicate incorrect URL structure, often seen during migrations from webdav to dav/files.
