I am trying to establish a connection to Koofr through rclone and my connection does not work. Why?

You need to generate an application-specific password in Koofr web app, to establish a connection to Koofr through rclone. See how to generate an application-specific password.

Note: Without an application-specific password, you will not be able to establish a connection to Koofr through rclone.

General note for using rclone with Koofr: Do not use --copy-links option with rclone when copying or syncing files to Koofr, since you might end up infinitely uploading your files over and over again if a cycle in the filesystem is induced by your symlinks or junction points.
