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

[Jpm]

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

hello, thansk for fast aswer,
i have made more test and i notice that if i make many tcp request on google or on any sites, i receive -1 but if i wait some seconds(30 s) some times i'll reveive corret sockets

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.
