TCPConnect() return always -1 on a public ip

[sainsuper@…]

hello,
using this code

$RepeaterIP = "www.google.it"
$RepeaterServerPort ="443"
TCPStartup()
$socket = TCPConnect(TCPNameToIP($RepeaterIP), $RepeaterServerPort)
MsgBox(0, "", $socket)
TCPShutdown()

Socket will return always -1 ( and @error isn't set)
if i use local ip address (like 192.168.x.x) it works.

Using beta version 3.3.15.0 it works
latest Autoit that working is 3.3.12.0

For me both Release and Beta are OK
Can you double check your environment?

i have compiled same code with different version of autoit 3.3.15.0 ( beta) and 3.3.14.2.
With beta version i always have socket. with 3.3.14.2 i often have -1 and only some times i have socket.

hello jpm,

i have checked my enviroment and after many test i notice that a hardware firewall in office block some connection for security reason. i have done test in other line and the problem isn't present.
thank you and sorry for the time lost.
