remote: GitLab: Push operation timed out

Question

I'm trying to fix my repository with BFG Repo-Cleaner, by removing some large files that were added to it, using this guide: https://rtyley.github.io/bfg-repo-cleaner/ . When I'm trying to push (a very large push), I'm getting: "remote: GitLab: Push operation timed out".

The output I receive when pushing consists of the following:

numerating objects: 12176, done.
Writing objects: 100% (12176/12176), 4.15 MiB | 3.89 MiB/s, done.
Total 12176 (delta 0), reused 0 (delta 0), pack-reused 12176
remote: Resolving deltas: 100% (8566/8566), done.

Is there any way to fix that?

GitLab no longer supports using BFG and now supports git filter-repo

In previous versions of GitLab, the repository cleanup supported using the BFG object map.

The current recommended procedure is

• Export the project
• From the bundle, bare mirror clone to a fresh repository
• Run the cleanup, using git filter-repo
• Force push the heads, tags, and replace refs
• Wait 30 minutes
• Run the Repository Cleanup using the commit-map in .git/filter-repo/

Then the cleanup process will remove all of the dereferenced files or commits.
