As I've mentioned before my server is behind a router and the only thing I'm not sure about is when I should use my public ip and when to use my internal ip when configuring the server and dns settings. Could an error in the ip settings create the problem I'm having?
Yes, if your IP settings are incorrect you might get this error.
If you are in a NAT eviroment, always use your internal IP address. Only in the ISPConfig DNS-Manager you will have to use your external IP.
