Port is opened in the firewall? Typically port 30,000
Emulator is correctly configured and is accepting connections on the same port you have opened. Verify emulator is running.
Verify all 3 of these things, then we will talk about more options.
I turned off the firewall to confirm that ports are opened, my emulator is tcp 30000 like client and connected perfectly in database, and I dont see problems in variables...
Can you help me on teamviewer? @JayCustom
