Could not connect via UDP (Only via TCP)

Hi,

I'm working on my server side project and I configurated all settings right to allow other people connect to my game server. When I said configurated all settings right, I meant that open ports on Windows Firewall, Router Firewall, and no anti-virus or something other that may block this connection.

On canyouseeme.org I can see an open port (a running service - photon server) with TCP but not with UDP.

I tried to see what's going on "netstat" from "cmd.exe" and there is a service which is listening to TCP and UDP:
0) 0.0.0.0:5057 - TCP
1) 10.0.0.2:5057 - UDP (Is remote IP translated to Local IP on communication?)

TCP and UDP configurated on a photon server config to listen on 0.0.0.0 IP.

Any ideas?

Thanks,
Ben.
