Issue

  • All repositories sync to the Red Hat Content Delivery Network (CDN) as expected through the environment proxy except for single repositories. Attempts to sync these repositories fail with the below error seen in /var/log/messages (where 123.456.789.111 is the IP of the proxy in the environment):

    pulp: nectar.downloaders.threaded:ERROR: Skipping requests to cdn.redhat.com due to repeated connection failures: 
    HTTPSConnectionPool(host='cdn.redhat.com', 
    port=443): Max retries exceeded with url: /content/dist/rhel/server/6/6Server/x86_64/sat-tools/6.2/os/repodata/repomd.xml
