Collabora Not Working With Cloudflare Proxy

We recently moves all domain hosting and DNS to Cloudflare. The domain privacy and security options were a huge plus.

We are having one issue though. The sob domain that servers our Collabora server does not function then enable DNS proxy. I searched and could not find any assistance with this. Collabora uses standard http and https requests, so I’m not sure if it’s a configuration issue or something else.

Can someone with more knowledge on Cloudflare infrastructure provide some insight into why this would not be working? Is there a solution?
