Andriod Mobile App "Connection to server refused"

Hi all,

I'm trying to setup my phone to connect to my SW server at my companies office but I keep getting the error "Connection to server refused".

I have my ports opened/forwarded on my modem > router > switch > computer.

For my phone settings I have:
IP: (our public IP)
Port: 9675
No SSL
My correct login information

Any help as to why I'm getting this error? Did I forget to enable something in SW itself?

Thanks!
