Good afternoon sorry for the spelling am from Venezuela and I have a antminer S4 and the problem is that it comes on but did not grab the Internet to connect I'm going crazy not to do please help me.
This topic belongs to mining section.

From what I can interpret is that your primary firewall is blocking its connection.
