Pipeline stuck but builds and tests passed

Hi all,

I have the problem that the pipeline of a specific gitlab ci runner thats not under my control is stuck forever. If I look at the details of the pipeline I can see that all builds and tests are passed so it looks like the only thing that’s missing is that Gitlab recognizes it. There is also no error in the console output of the builds and tests. Do I have any chance to debug it on the Gitlab server?
The runner is installed on a mac mini and was restarted but the problem still resists.
Thanks for any hint or tip && have a nice day!
