Running teamspeak through cloudflare - 9987 working but port 10011 is not working

[unable to retrieve full-text content]

Any idea why my port 10011 is not working when running through cloudflare through a subdomain instead of the direct IP address? the port 9987 works fine, people are able to connect to my server. Only the udp got an srv record though. maybe i miss something? Running teamspeak through cloudflare - 9987 working but port 10011 is not working
