I can't push after garbage collecting dead data (2gb < size of repository < 5gb)

Hi

    With my last commit, I accidentally exceeded the 2GB limit

    after which I did the following:

1. git reset --hard HEAD~
2. tried "git push --force", but size of local repo didn't change, so it was pointless
3. git reflog expire --expire=now --all
4. git gc --prune=now

    On this stage size of local repo +- 200MB, but "git push --all --force" not works

fatal: TaskCanceledException encountered.
A task was canceled.

    Just in case: I'm not the admin of repo

   Sorry if this problem already was, but I can't search it 

Thank you in advance!
