Hi all
Port 80 being blocked seems to be the only culprit.
In Windows7, open CMD and type this:
netstat -o -n -a | findstr 0.0:443
also type this
netstat -o -n -a | findstr 0.0:80
Results were:
---
TCP 0.0.0.0:443 0.0.0.0:0 LISTENING 692
UDP 0.0.0.0:443 *:* 692
---
and
---
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 692
---
Application PID 692 was skype.
Exiting skype solved the issue immediately.
