Ethernet shield not connecting to the Webserver - new to Arduino

My bad. Always check the simple stuff first. Are you using this ip for the server?

byte server[] = {31, 170, 160, 99}; // My webserver IP

I show your domain hosted at this ip

byte server[] = {31, 170, 161, 36}; // My webserver IP

I used nslookup to find your ip.
