I want to use cell phone when the client send messages to a computer, but not on the computer like mobile phone (two projects at the same time in the computer test can normal transfer), if the phone when the service side, when the client computer can normal communication,
The server and client code is written in the script for the unity,
Why will appear this kind of problem, is that what permissions didn't open a computer, or a problem with the IP address?
Sorrow bald head... For bosses to solve! Be urgent! Online etc.!

Hello ~
Even the same WiFi, cell phones and computers IP address is on the computer, after manual input by the input field, but mobile phone card in the connection here

CodePudding user response:

It is know that in general the debug, the feeling of your description is not in the same local area network (LAN), it could also be a firewall problem
