Issue installing Collabora following official guide

My setup is where I have a dedicated Apache server in front of all my other VM’s. Is this a supported setup for Collabora? Since the guide state using 127.0.0.1 which means the apache doing the proxy is on the same machine. Which in my case isn’t valid since I have my Apache on a separate VM.

I have switched from devicemapper to overlay FS. But still get the error:
