Collabora Online not fully loading

Hi, hope their is someone here that is able to point me in the right direction. I have been working on this for a few weeks without any luck in resolving it.

Firstly the environment:
Nextcloud is running on its on proxmox VM running ubuntu-20.04.1-live-server-amd64
Nginx is running also on its own proxmox VM running ubuntu-20.04.1-live-server-amd64
Installed Collabora on its own proxmox VM, also running ubuntu-20.04.1-live-server-amd64
using the following tutorial as a guide: link
Please note: that this tutorial differs from my environment as it installs Nextcloud, Collabora and NginX on the same VM.

The issue:
As I use different VMs, I first tried to configure Nginx by adding a new conf file called and adding the values mentioned in the tutorial to it. This did not work for me as Word documents would not open and would only display a white page.

Then, I decided to removed the specific collabora code from the Nginx and created the reverse proxy using appache2 on the collabora VM itself as described in the tutorial. This got me a step closer to resolve, as collabora would load more than the white page before.

As you can see in the below screenshots, it will load collabora mostly but than stops:

I cant figure out what is going wrong.

Hope someone can help me get it to work. :slight_smile:

Thanks so much.
