MR not showing commits being pushed to repository

Hi,

I´m having an issue with my onprem gitlab instance.

I’m getting this errors when pushing to a repository:

# git push
Username for 'https://gitlab.local': xxxxxx
Password for 'https://my_user@gitlab.local': 
Enumerating objects: 5, done.
Counting objects: 100% (5/5), done.
Writing objects: 100% (3/3), 259 bytes | 259.00 KiB/s, done.

remote: error: cannot lock ref 'refs/heads/1-test-push': is at 20597970dee76c610869d452b396c263ae36039d but expected dca88ff561e19920ffc956416f7aaaa2cd57955e

 ! [remote rejected] 1-test-push -> 1-test-push (failed to update ref)
error: failed to push some refs to 'https://gitlab.ibm.lab/fmtrasan/test-project.git'

Steps to reproduce:
1 - Create a new project.
2 - Create a new issue and a MR with a branch.
3 - Clone the repo from the branch issue or checkout that branch issue.
4 - make a change and commit.
5 - push the change.

I get that error, if I push again I get an “up to date”, but when I go to the MR I don´t see the commit on the history tab, but If I go to the branch History, it is there.

This started a few weeks ago, the version I´m running now is 14.5.2-ee.

I don´t know if I’m doing something wrong or there is a bug, because up till this started happening, always worked the same way.

Any input would be appreciated.

Regards,

Update,
For me at least, that error could be due to a networking problem, we have some issues on our network that produces a lot of retransmissions, and all https and ssh connections have random errors.
