Externe Runners get stuck on every job with "Appending trace to coordinator... failed code=501"

We are running GitLab CE in an on-prem deployment. Runners within the LAN are working perfectly fine on various OSes.
Now we configured reverse proxies to make the on-prem deployment reachable from the Internet to do some magic with MacOs and Swift. Strangely though, out GitLab runners on Mac (and Linux for testing) are able to register and pick up jobs, but seem to fail to report the job status back to Gitlab.

This is what it looks like in our docker bases runner on a Mac when we try to run a sample pipeline with nothing more than a simple echo in a shell:

Using Shell executor...                             job=233 project=146 runner=********

Within Gitlab the job is marked as “Running” but never finished.

Does any of you have an idea how to troubleshoot this and what might be the reason for the “Appending trace to coordinator… failed” message?
From my understanding, the “Failed to parse “X-GitLab-Trace-Update-Interval” header” message is more or less cosmetic in nature and can be ignored.

Thanks in advance for your thoughts and ideas!

Cheers

We too run gitlab on premise and we use kubernetes runners we do see such warning and the job hangs without processing any further.

Hi,

which versions of GitLab and the CI runner are involved here? I suspect that either one of them differs and possible the runner being too old does not parse the header correctly.

Hi @dnsmichi Gitlab version is 13.0.5-ee and gitlab runner is 13.0.1(we have deployed the runners using helm chart. Chart version 0.17.1)

Hi,

We are seeing the same problem. Sometimes jobs just stuck in running state in Gitlab and nothing is shown in Gitlab runner log.
When the job is cancelled and retried, then something appears on the gitlab runner’s log.

Here’s the relevant part of the log:
