I am trying to reduce the size of my repository, currently about 9.7GB. So I proceeded as follows:

1. Export the project bundle from my repository.

2. extract the downloaded project bundle.

$ tar  xzf 2022-02-22_12-50-017_my_project_export.tar.gz

3. Clone the export project bundle.

$ git clone --bare --mirror project.bundle
Cloning into bare repository 'project.git'...

4. Change to project.git repo.

$ cd project.git

5. Analyze repo.

$ git filter-repo --analyze

6. Purge files larger than 50M

7. Delete remote origin

$ git remote remove origin
Note: Some branches outside the refs/remotes/ hierarchy were not removed;
to delete them, use:
  git branch -d dev
  git branch -d master

$ git remote add origin https://gitlab.com/my_project.git

8. Force push your changes to overwrite all branches on GitLab.

$ git push origin --force 'refs/heads/*'

Can you suggest how this could be resolved?

No answer to this yet…?

Dear Community, can someone help on how to fix this…?

For a few days I am trying just to make an initial push any local branch to remote origin, and always failing with similar error:
Writing objects: 100% (15081/15081), 1.78 GiB | 5.75 MiB/s, done.
Total 15081 (delta 8503), reused 15018 (delta 8459)
error: RPC failed; HTTP 524 curl 22 The requested URL returned error: 524
fatal: the remote end hung up unexpectedly

I have another repository with the same setup that is working just fine (so network issues are not a problem). And problematic repo has lots of files with >10MB size, maybe this is the problem?!

It is worrying that GitLab has no fix to this problem yet.
