Question

Jenkins Cross-Origin-Opener-Policy header has been ignored

As I was following through the tutorial for Jenkin’s Installation (https://www.digitalocean.com/community/tutorials/how-to-install-jenkins-on-ubuntu-20-04), I successfully installed Jenkins.

But when I access Jenkin’s login page, I’m getting an ‘The Cross-Origin-Opener-Policy header has been ignored, because the URL’s origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the ‘localhost’ origin instead. See https://www.w3.org/TR/powerful-features/#potentially-trustworthy-origin and https://html.spec.whatwg.org/#the-cross-origin-opener-policy-header.
