The port is not opening, what could be the problem?

Question

Computer networks

The OS is the usual seven, the cable is connected directly, the firewall is turned off, the antivirus too, this port is open on the provider side (4444).

Answer 1

no stat check if this port is already in use by something? if not, then you need to look for a problem in the white ip, because as with Windows, by default, all unused ports are open.
