I am using rclone v1.55.1 on Ubuntu 20.04 x86_64 GNU/Linux and having an username/password incorrect response in the middle of the sync process of a personal webdav (Owncload) server:
[myServer]
type = webdav
url = https://myServer:PORT/remote.php/webdav
vendor = owncloud
bearer_token = ****
user = my_user
pass = *******
This issue can be reproduced by a simple rclone lsl myServer: command:
rclone lsl myServer:/Resources/Softwares/USB-serial # Returns fine

rclone lsl myServer:/Resources/Softwares/ # Starts fine but fails on the middle.
