I am trying to set up new Jenkins. When I download Suggested Plugins OR try to install any plugin I am getting below error. I am using Jenkins Latest Version 2.204.1. I have set up this on VM. I am getting this error for all the plugins even when I am trying to install suggested plugins during the initial setup, that time also I am getting the same error. I am installing Jenkins on Microsoft Windows Server VM. I have downloaded Jenkins from Browser, extracted zip file and installed it using jenkins.msi.

You can try 3 different things-

  1. Try pinging https://updates.jenkins-ci.org/download/plugins/ and see if it gets any response. If it doesn't respond then make sure your internet is working fine.
  2. You can try installing the plugins by connecting to a VPN.
  3. Lastly, you can reinstall Jenkins to see if the error persists.

I have to reinstall the Jenkins 2-3 time and it starts working, but at an initial level still, I am not able to install suggested plugins. I have setup Jenkins first and then installed all the plugins manually.
