Access Selfhosted Community Docspace Using Cloudflare proxy

Question: Can DocSpace be accessed using cloudflare proxy.

Versions:
Document management: ONLYOFFICE DocSpace v.2.5.1
Online editors: ONLYOFFICE Docs v.8.1.0.169

Setup: LXC Ubuntu container deployed on proxmox. I am able to access DocSpace on LAN but I have installed cloudflared and have a subdomain connected to it.

When I try accessing my Docspace, I end up with an error: Gateway time-out Error code 504
I also tried updating my custom domain name but no joy.

Hello @pmz :wave:

To get started, please specify the type of ONLYOFFICE DocSpace installation you are using (exe, Docker, deb/rpm).
