The program cannot internet connection

Hi,

Can someone help me? Why can’t the program connect to the internet?

Avast firewall settings are appropriate.

Hi,

I have tried to follow the instructions but still can’t. To my surprise, there are several computers that can work well. Why did it happen ?

Thank you

So, does it work if you disable the Avast FW…?

Yes, It’s work if I disable Avast Firewall or I set default rule firewall “ALLOW”. Even though all configurations are all the same.
