JetBrains TeamCity CI stopped sending merge requests triggers

General
1

I had this setup for half of a year and it worked flawlessly.
But starting from 2nd of April I have problems with it. Gitlab does not send MR events to my TC server.
I have only “Merge Request” trigger enabled.

How do I reproduce:

  1. create feature branch
  2. create merge request of this branch into develop branch
  3. Nothing happens

Expected results - TC pipeline is started.

When I activate push triggers - it starts working. But this solution is not acceptable.
When I push “Test settings button” - TC pipeline is started.

My TC is behind reverse proxy, so I also checked logs of it. When I use push trigger and “test settings” button - I see connections from gitlab addresses to my TC.
But when merge request trigger should be activated - there is no connection from gitlab addresses.

I did not find any information how to debug it from gitlab’s side.
Help please?

same situation. all work fine on 13.7.4, but today i’m upgrade to 13.12.9 and pipiline on merge request was broken.
i hope that upgrade to 14.x fix this issue but i can’t try it now

but no luck.
after upgrade to last 14.2.3 still no build triggered by merge request
then i press ‘test connection’ on teamcity integration in gitlab i see new build in default branch was starting,
but then i create merge request no new builds…
i check teamcity logs - no info about incoming request, so i think that is problem on gitlab side.
i also check gitlab logs but not found any related warnings or errors

GitLab Community Edition [15.1.2] still no build triggered by merge request…

I don’t see moving by issue :frowning:
