RD Gateway custom port

Question

I am setting up RD Gateway on Windows Server 2019 to run on non-default port.
Settings applies, i can see correct bindings in IIS site and active listening port on the server. Also checked registry values - all correct
But clinet connection from Windows 10 RDP client with RD Gateway serverFQDN:port fails (with default 443 port connection successfull).
New custom port is available, I can access it via telnet
IIS Site opens on new custome port
Any ideas?
