We notice intermittent failures to access to jenkins-ci.org or pkg.jenkins.io (jenkins-ci.org is redirect on pkg.jenkins.io). I first believe it was a network issue in the network of my company (based in Italy). But same errors occurred on an external unfiltered line (based in France). I discover the problem because we ran automatic installations of Jenkins with ansible and we installed a lot of jenkins' plugins. Most of the time installation failed because we got a network errors.
The problem could be reproduced using curl command (see full trace in attachment). curl -XGET -v -L https://jenkins-ci.org/redhat/jenkins-ci.org.key

Do you have any information about these failures? Is it possible to find a workaround?
Do not hesitate if you need more information, I can perform additionnal tests.
