    • Jenkins latest; no plugins; Windows Server 2016 Standard; Any web browser; Oracle JDK1.8;

      Brand new Jenkins instance is behind corporate proxy. Test URL passed, but checking plugins ends in "There were errors checking the update sites: FileNotFoundException: http://updates.jenkins.io/update-center.json?id=default&version=2.176.3", see screenshots.

      This URL is normally available in browser. When "Use browser for metadata download" ticked, I'm able to browse plugins but I can't download anything. I tried update mirrors (mirror.serverion.com) as update URL but still nothing.

          Also, I'm puzzled by your statement that you're using a brand new instance. I'd expect you to be using https://updates.jenkins.io/ (note the https). Can you explain why that s is missing?

          It might be a temporary mirror issue though we need more information to triage it

          There was a change made to the update site which broke it on http,

          It's highly recommended to run it on https.

          But that specific change was reverted
