Status: Resolved (View Workflow)
Resolution: Not A Defect
Due to firewall restrictions I'm using the "Use Browser to download Meta Data" feature.
This allowed me in the past to view all updates available for jenkins, even though the server itself has no internet access.
Since the last update to 2.77 this feature stopped working.
When opening the browser console I get the following error:
Mixed Content: The page at 'https://xxxx/sbjenkins/pluginManager/checkUpdates' was loaded over HTTPS, but requested an insecure resource 'http://updates.jenkins-ci.org/update-center.json.html?id=default&version=2.77'. This request has been blocked; the content must be served over HTTPS.
I'm pretty sure this is a legacy setup that has an HTTP update site URL configured.
davidgiga1993 Manage Jenkins » Manage Plugins » Advanced. What's the URL at the bottom? What happens when you specify the equivalent https url?
danielbeck Doh, this fixes the issue. Sorry for overlooking that option. I was assuming the protocol changes automaticaly when you define "https" as jenkins URL.
rtyler danielbeck Likely it has been caused by https://github.com/jenkinsci/jenkins/pull/2996 .
Probably the update center configuration in Jenkins needs to be updated in order to use the HTTPS address.
