      I entered proxy configuration in Jenkins > Manage plugins and successfully tested the configuration.

      But I'm not able to do updates, because the proxy authentication does not work.

      There were errors checking the update sites: IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 authenticationrequired"

      The update site URL is working fine in proxy configuration test (see screenshot, Test: Erfolg=Success, Update server: error)
