Hello,

Could this be linked to the brownout?

Really strange. I can download the json list using wget. I need to
check if this list is consistent

Not a dev list question, I recommend you report this to https://github.com/jenkins-infra/helpdesk/

As a workaround I would try replacing the protocol with https, and the host name with updates.jenkins.io in the plugin manager configuration; you're still on the default URL from 7+ years ago.

[Michael Kriese]

Hi,

saw same issue today and realized that the default url still points to http.

Resetting the url to default value fixed the issue.

Maybe there should be a warning / notification if the update center url points to an old jenkins url (and isn't reachable).

Regards

Michael

[Damien Duportal]

Hi folks,

This is definitively related to our operation https://www.jenkins.io/blog/2024/09/10/update-center-brownouts-3/.

I'm wondering where would this default HTTP would come from: I just started up a fresh Jenkins 2.476 from the WAR and it uses the HTTPS by default (with the "updates.jenkins.io").

Are you using a rather old version of Jenkins? Or do you have a custom UC URL enforced?

The brownout will stop around 02:00pm tonight, but we most probably will enforce HTTP to HTTPS redirection in the old Update Center VM (as we did with mirrors 2 years ago).

Cheers,

Damien DUPORTAL, for the Jenkins Infra team

[Michael Kriese]

I don't really know.

I migrated my jenkins from windows to linux docker a long time ago and upgraded a lot of times.

Maybe i had saved the update center url somewhere between.

I do dist-upgrade every release ;). My CI work always with the latest
plugin and jenkins

It’s from old instances Damien, we’ve hit similar issues before

Many thanks for your help and responses folks!

Looks like Stefan, in https://issues.jenkins.io/browse/JENKINS-73760?focusedId=449268&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-449268, caught that this URL was the default URL in ancient times.

Most probably you've inherited the setup across upgrades, which is kept (and not migrated) over Jenkins upgrades while a fresh install uses the new URL (or i missed something else ;) ).

=> worth switching to the default https://updates.jenkins.io as pointed by Daniel.

(I'm still wondering why the redirect is not followed by the internal Java client. Might be the 308 code :thinking:)

[Stefan]

Just chiming in here as well: AFAIK the default Java behavior is to not switch protocols during redirects to avoid security issues - even for HTTP to HTTPS switches -, as pointed out in https://issues.jenkins.io/browse/JENKINS-73760?focusedId=449264&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-449264
