I'm having the exact same issue, started last Friday (July 12).
I won't bore you with my logs because they are exactly the same as OP's, except for this:
Some additional info: I was able to mount Pikpak in rclone over their webDAV protocol service, where I can download all the files I currently can't with the regular mount.
However this is only a temporary fix, because their webDAV offering is not ideal as it doesn't allow uploads.
Hello everyone,, did anyone managed to solve this issue? It's impossible to retrieve data from the PIKPAK cloud and Ubuntu CLI.
Download can't even start it just checks the file list and after 25-30 sec I get the error:
filename.partial: Removing partially written file on error: unexpected EOF
Uploading to the cloud storage on the other hand works just fine.
Any info about mentioned error would be a great help an appreciated.
