What is the problem you are having with rclone?
I am unable to upload files to Proton Drive. Every write attempt fails with a specific error loop:
- The initial POST .../blocks fails with Code=200501 (Operation failed).
- Rclone retries, but Proton now reports the file exists (Code=2500).
- Rclone attempts to check revisions to handle the conflict, but fails with Code=2501 (File or folder not found).
This results in "zombie" files on the remote that have a name but no content/revisions, blocking further uploads. I have already
tried rclone config reconnect proton:, which fixed ls and about (I can read files and see quota), but uploads still fail consistently for any file.
Run the command 'rclone version' and share the full output of the command.
