Proton Drive unable sync/copy anything

welcome to the forum,

Rclone uploads failing to Proton Drive

Sorry guys but there is nobody at the moment looking after Proton remote. Existing implementation has been reverse engineered (due to lack of proper API and documentation from Proton) and original developer went quiet long time ago. The best what you can do is to lobby Proton to officially allow 3rd party tools. Or even better to open their drive to some standard protocols like webdav or sftp. Also see just posted:
