Update Jenkins & Installing Plugins on UI

Hello everyone,

Based on the official article below, we’ve allowed 20.7.178.24 IP address on port 443 on the firewall. However, I’m having trouble installing plugins and recieving latest Jenkins updates/upgrades. https://www.jenkins.io/blog/2023/06/22/mirrors-jenkins-new-IP/https://www.jenkins.io/blog/2023/06/22/mirrors-jenkins-new-IP/

In Advanced setting I set the website :
Update Site
URL

https://updates.jenkins.io/update-center.json

I don’t know why any admin didn’t answer my questions ? I need all Jenkins IP address for installing plugings and update/upgrade Jenkins
!!!

Because the Jenkins infrastructure team is very busy with other work that keeps the Jenkins project running and healthy.

I’m not sure that there is a list of all Jenkins IP addresses for installing plugins and updating Jenkins. The updates.jenkins.io site includes a page that lists most recent releases. If URL’s from those most recent releases are extended with the ?mirrorlist query parameter, you’ll see a page that shows the Jenkins mirrors.

For example, the URL https://updates.jenkins.io/latest/jenkins.war?mirrorlist shows a page like this:
