How to diagnose connection issues

I have set up a SoftEther VPN server on a Windows 7 machine, but not been able to connect to it.
The machine is behind a router (FiOS-G1100). I am wondering if there is log that I can check to find out why connections fail.

The obvious first questions are: have you forwarded the port through the router to your SE server ; have you also checked that the Windows firewall is not blocking your connection?

Thanks for trying to help, Fenice.

I first tried VPNAzure because I thought it did not require any port forwarding. After it failed, I forwarded port 992 to the Windows 7 machine running the SE server, then used the DDNS address, but failed too. Port 443 has already been used. I noticed that the following ports are being listened to from SE VPN Server Manager:
992
1194
5555

Is forwarding port 992 sufficient? Does VPNAzure also need port forwarding?

This is my first time to use SE. It appears to be a great product.

Edited:
I have tried disabling the Norton Firewall. When I use the DDNS address, I appended the port like the following:
myname.softether.net:992

Also please forward ports 500,4500,1701, 1194 just to be sure

What client do you use?

You can check the server logs in virtual hub dialog in SoftEther VPN server manager.
