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/](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](https://updates.jenkins.io/update-center.json)

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](https://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:
