The CI system posts results to Gerrit changes itself as well as on https://testresults.qt.io/coin/ . Those results contain links to the changes that were attemped for the integration. Here's a simple example of a recent (failed) attempt:

https://testresults.qt.io/coin/integration/qt/qtbase/tasks/1558649467

The links to the changes look like this:

https://codereview.qt-project.org/#/q/a5bc7c8d7e790739326cc250f2290dd7cf3225be,n,z

or generally

https://codereview.qt-project.org/#/q/<change-id>,n,z

Unfortunately these links do not work anymore.

Acceptance criteria for this ticket:

(1) Gerrit accepts HTTP requests for the above described format again and redirects to the page that shows the change.

or

(2) Coin is changed to use the new URL scheme for changes based on the change-id.

I would prefer (1) as the Coin archives do provide value and it would be a shame if they become useless.
