this is probably a newbie question, but I won't learn if I don't ask :)
I have a ubuntu webserver that hosts my website, and I have a no-ip account that provides the hostname.
I was able to access the website earlier today, but now I am unable to access via the hostname via my laptop, or smartphone. When I do a ping, it cannot resolve the hostname. When I do an nslookup on the hostname, it times out.
I am able to resolve via my external IP address, the internal IP address, as well via the webservers hostname, which confirms that apache is up on the server, and that the webserver is at least on lol.
I think it's a DNS issue, but I'm not sure what to check from here to be sure. Please advise if any more information is needed. Thanks in advance!
