TCP Stream with SSL + HTTPs on different port

[maxdd]

I have a domain which i normally use to expose my service.
I have a proxy-host on port 8123 with ssl.
Can i also create a TCP Stream with the same domain (and certificates) but on a different port?
When i do so my https service become unreachable with error "400 Bad Request" while the tcp stream still works.

Resolved, the issue was in my service not trusting a reverse proxy connection
