tcpclient - Cloudflare - normal TCP connection "bad request"

Question

This question is only related to Cloudflare Proxy

Trials:

If I try to establish a connection to mydomain.com:8443 through the browser it works But if I try the same but using an ownmade TCP program, it disconnects before hitting the actual server.

Note that using the ownmade TCP program works if I turn off the orange cloud (proxy)

Errors:

So I used wireshark to see what happen and it turns out Cloudflare blocks the connection with error code 400 Bad Request

Thoughts/Questions:

Is there any settings in Cloudflare I can fiddle around with to forward it to the server regardless if it is a "bad request" (while keeping orange clouded proxy on)? Or am I forced to re-write the program to start a Websocket instead?
