Server-Scripts | This is a collection of scripts

Presumably when it compresses objects it puts them somewhere temporarily, then in a separate action tries to move them to their permanent location. Moving them means copying them from the temporary location to the permanent location, then either deleting them from the temporary location or leaving them to be removed by other processing, possibly at another time. For example, many of the files and directories that get written to the /tmp directory in Linux are customarily left there, until the operating system removes them upon the next reboot (if there ever is a reboot).

The failure looks like a lack of permission to write to the remote location. The failure occurred when git tried to move the objects that it compressed to the remote location https://git.patrikx3.tk/server-scripts.git that you would have specified in the project's configuration. Less likely, you could have specified it in the command or (I think?) in your global configuration.
