Unable to push tags to Gitlab Community


We’re experiencing issues pushing tags from our Jenkins machine to Gitlab, after a migration from Github. The error reported is as follows:

cmd: git push --tags
output: ! [remote rejected] master -> master (pre-receive hook declined)

Branch involved here is develop; our master branch.

Troubleshooting we’ve done so far:

  • Checked SSH keys; these seem correct. We can pull, push (without tags) normally.
  • Checked write ability of SSH keys; checked, toggled as test. No result.
  • Checked network; See above, seemingly no problem.
  • Added new SSH keys as test; no changes.
  • Disabled protection on master branch. No changes.
  • Checked and verified protected tags were off. No changes.
  • Disabled/enabled keys by means of test.

What might it be, and what other tests can we do to isolate the issue?
