Hi Horst,
yes I checked and the issue is in Eoan 2.4.41 - I checked that already last 
week and let Steve now.

Steve wanted to track the upstream discussions on this as going forward
we most likely want to follow upstreams guidance on this (e.g. want to
have it broken for better security).

But thanks for the ping, we might want to mark the bug tasks accordingly
to make this clear.

Bug description:
  OS

  Description:Ubuntu 18.04.3 LTS
  Release:18.04
  Codename:   bionic

  
  I use this kind of configuration to reache the Balancer Manager.

   -
  |Bastian Host |
  |Apache Proxy | ---> LB Apache Balancer Manger
   -

  After Apache Update

  from: 2.4.29-1ubuntu4.8
  to:   2.4.29-1ubuntu4.10

  The Balancer Manager behind a Proxy is not Working and i think this is 
comming with
  the fix CVE-2019-10092

  https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2019-10092
  
http://changelogs.ubuntu.com/changelogs/pool/main/a/apache2/apache2_2.4.29-1ubuntu4.10/changelog

  
  I strip down the configuration to try and explain the situation.

  Install new Ubuntu 18.04 VirtualBox. From an another VM i saved the prior
  Apache Packages from /var/cache/apt/archives

  At that point i install also some console Browsers for testing.

  :~# apt-get install lynx elinks

  :~# tail -f /var/log/apache2/management_error.log

  :~# elinks 127.0.0.1:81/balancer-manager
  :~# lynx 127.0.0.1:81/balancer-manager

  i can do update the Load and made changes. i also connect from outside with
  Firefox
