      Proxy configuration doesn't work even if 'check proxy' works! No workaround found.

      Situation: Fresh installed Windows Server 2016 with latest, fresh installed  LTS Jenkins version 2.89.2. Server is behind a proxy. Check of Jenkins proxy configuration says 'Ok' but checking plugins crashes jenkins (see attached screen shot).

      I have a second machine (Windows 7 enterprise) with the same Jenkins version, behind the same proxy, with (really!) the same proxy configuration: Check Jenkins proxy settings says: "Error 407", BUT: Checking plugins works! (WTF!?!) One differrence is the java runtime verision: on this machine = 1.8.0_66-b18.
