Internal Server Error 500 while accessing $GITLAB/admin/runners

runner
ci
#1

I have restored Gitlab from a backup, now every time i try to access the runners webpage, I get a Internal Server error.

I have tried uninstalling all configured gitlab-runners and accessing it, the problem persists. Here is a trace from the gitlab-rails/production.log:

I have tried reinstalling using docker as well as omnibus, the issue exists only after restoring any backup that I currently have. Is there a way to reset the runners from the command line or API?

@NerdSec I am having the same issue after upgrading from 11.4.3 to 11.6.5.

Did you manage to find a resolution to this?

Thanks,

Sean

You can reset runner`s token by:
sudo gitlab-rails runner -e production ‘ApplicationSetting.current.reset_runners_registration_token!’
