Testing TCP Port 443 on host The specified port is either blocked, not listening, or not producing the expected response.
I have ran portqry netstat everything has 443 listening for replys. When i run a test i get its not responding. I have a sonicwall firewall that has 443 port opened. I don't understand why it would not be able to communicate.
A network error occurred while communicating with remote host
Message: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 188.8.131.52:443
at System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port)
I brought this old thread backk to life because I have the same exact problem.
I can't Telnet to the port either and I can't get any smartphones to connect.
I have verified firewall connection and made sure IIS is running. Any other ideas
I could try?
Can you confirm everything is working fine within the network behind the firewall? If you have a wireless try connecting you Windows Mobile and then try to sync from within your internal network and see if it works. You can also use Windows Mobile emulator (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=3d6f581e-c093-4b15-ab0c-a2ce5bffdb47&displaylang=en) to check if it is working fine internally. On both you can enable verbose logging which can provide more infromaton. Assuming that you have configured the firewall correctly if it is not working internally it won't work from outside.

Check the Access Rules under VPN to ensure that http and https is enabled and
forwarded then look at what port you are using for Administration. Sonic
usually enables port 80 and 443 for the default administration ports. Try
moving those to a different port like 82 and 446.
