Jenkins latest stable 2.160 on CentOS 7
Tomcat v9.0
Very similar to JENKINS-28157
I changed the update-sites to update-center.json but it still tries to download plugins from
updates.jenkins-ci.org.
```

[JENKINS-55680] Update site does not change where to download plugins
As of August 2020, Jenkins update center now delivers plugins with HTTPS.

added a comment - We are facing the same issue. We have a local repository https://XXXXX.org.com/artifactory/simple/jenkins-updates-generic/update-center.json. I configured this URL to the UPDATE SITE. However, when i tried to install a plugin, it still routes the traffic to updates.jenkins.io. Is it not suppose to look for the plugin in the local repository?

I believe that Jenkins reads the contents of the update-center.json file and uses the URL's that it reads from the JSON file to retrieve the plugins. Have you replaced all the references to updates.jenkins.io and get.jenkins.io in the update-center.json file on your local copy?
A recent change to our network now blocks all traffic over http so I setup Nexus to mirror the Jenkins plugin site and configured it in Jenkins.
While Jenkins is able to pull in the latest updates.json from Nexus it still tries to download the plugins from http://updates.jenkins-ci.org, which is blocked by our firewall.
