404 when viewing pipeline after upgrade


After upgrading from 13.12.5 to 14.0.7, we are no longer able to see the results of a pipeline by clicking on it:
Clicking on 215834 above takes us to a URL ending in /-/pipelines/215834, which returns a 404.
Any idea how we can fix this?

I should add that the pipeline (a Jenkins integration) works fine, it’s just the link in the Gitlab UI in the screenshot that doesn’t.

We’re having the exact same problem, also using the Jenkins plugin. Did you found a solution?
