Zammad and ispconfig 3

Hello, what do I have to do to make zammad work with ispconfig 3? I installed ispconfig 3 and zammad, but I couldn’t get ispconfig to assign its address, I only entered zammad via IP. Thank you

It is discouraged to install Zammad on systems with managed webservers like ispconfig and plesk, as they may unexpectely remove configurations for Zammads proxy.

It is also discouraged to use Zammad via IP, as you’d usually not use HTTPs in that step which you definitely should do.
