I'm currently setting up Cloudflare for my domain and using their proxy feature in all my subdomains.

I have a remote desktop service called TSPlus Remote access, which we access to it through the browsers. I've already configured a reverse proxy to redirect the traffic and works well but the moment I enable the proxy feature in Cloudflare it just says when is trying to set up the remote connection "Alert! Connection interupted".

I've already tried many things that Chat GPT said and I already have the websockets option active in my Cloudflare's configuration.

The only helpful reference I found searching was this:

https://support.tsplus.net/support/solutions/articles/44002537252-html5-internet-access-alert-connection-interupted-establish-connection

So someone knows what to do?
