I am trying to upload a file (myvideo.mp4) to Linkbox using rclone but I keep getting the error: Failed to copy: Failed to copy: Update second step failed: Linkbox error 500: user upload file not exist
I also get HTTP error 522 sometimes when trying retries. I tried using the official Linkbox API for uploading as well, but I get the same response repeatedly.
Run the command 'rclone version' and share the full output of the command.

I also tried using the official Linkbox API for uploading, but I get the same response every time.
What I have tried so far:
Checked the file exists locally.
Verified my Linkbox remote is configured correctly in rclone.
Tried multiple upload attempts.
Tried the official Linkbox API manually.
I would appreciate any guidance on:
What this error means exactly.
How to fix it or troubleshoot further.
Whether there is something wrong with my rclone configuration or with the API usage.
already exists in Linkbox, rclone successfully uploads it by renaming it (e.g., adds (1)),
previously existed but was deleted from Linkbox, the upload also succeeds.
So the problem only occurs for completely new files that were never present before.
I also tried using the official Linkbox API manually but got the same 500 error response.
It seems like the Linkbox backend in rclone is not properly initializing uploads for new files, or the file entry is not being registered on the server during the first step.
