<p>You can try 3 different things-</p>

<ol>
<li>Try pinging <a href="https://updates.jenkins-ci.org/download/plugins/" rel="nofollow noreferrer">https://updates.jenkins-ci.org/download/plugins/</a> and see if it gets any response. If it doesn't respond then make sure your internet is working fine. </li>
<li>You can try installing the plugins by connecting to a VPN.</li>
<li>Lastly, you can reinstall Jenkins to see if the error persists.</li>
</ol>

<p>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.</p>

<p>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 <strong>Version 2.204.1</strong>. I have set up this on <strong>VM</strong>. 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.</p>

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.
