Issue

• Is there a way to force the plugin updater to use the HTTPS version of the update site (e.g., https://jenkins-updates.cloudbees.com/update-center.json)?

Environment

Resolution

Starting from the Release 2.89.4.2 CloudBees Update Center service is consumed using exclusively HTTPS. Therefore, all the currently supported releases should download plugins exclusively over the secure connection.

See CloudBees maintenance lifecycle for currently supported releases.
