Random disconnect from server, Now I cannot connect?

[DeepNote 1]

Hello guys, I've been using Emby for a while and its pretty good. However yesterday I was connected to my server through my DDNS which I setup with NO-IP and last night I randomly disconnected, and couldn't get back on the server? I originally had my computer DMZed, I know its not the best however I dont have to available for everyone just me. I can connect via LAN with localhost however when I try connecting via my external IP it doesn't connect at at all? I tried without the ddns address as well and still I cant connect? The strange thing is is that it just stopped, initially I didn't do any changes in settings other than update the server 2 days before but still it was working until last night? If anyone could shed some knowledge to help this poor fool, I'd greatly appreciate it. Thank you again.

Do you have a static IP address on the server machine itself?

 

If not, perhaps its internal IP address changed so now your router port forwarding rule is wrong...
