Great. This means the remote host did not respond to your connect 
request. I'm not suprised others see this as well :-)

One possible solution would be to get the remote host responding ;-)

Or more seriously: you might have a problem with transmitting or 
receiving tcp segments. I assume your lwip port or something else is new 
and untested. Wireshark is your friend in that case ;-)
However, it could be also just be a non-existing IP address...
