I always get a 404 error while I try to access the Update-Center file

Issue

When I try to access the update-center.json file, on https://jenkins-updates.cloudbees.com/update-center/operations-center/update-center.json, I’m always getting a 404 error status.

Environment

CloudBees CI (CloudBees Core) on modern cloud platforms - Managed controller
CloudBees CI (CloudBees Core) on modern cloud platforms - Operations Center
CloudBees CI (CloudBees Core) on traditional platforms - Client controller
CloudBees CI (CloudBees Core) on traditional platforms - Operations Center
CloudBees Jenkins Enterprise - Managed controller
CloudBees Jenkins Enterprise - Operations center
Jenkins LTS

Resolution

In order to be able to provide a Update Center file for each core version, a query parameter is mandatory on this URL: version. So, if you are using an Operation Center with version 2.204.1.3 you need to use the url https://jenkins-updates.cloudbees.com/update-center/operations-center/update-center.json?version=2.204.1.3.
