100% packet loss

[joel13]

pinging how (by LAN IP? public IP? FQDN?) and from where (inside or outside the LAN?)

Outside of the LAN. Users can still access the site and view web pages but whenever it is pinged/data is posted to the request just times out.

But I'm still getting 100% packet loss when pinging the server

Well, the issue is NOT with the server networking.
I would draw a picture including all the points that matter, then trouble shoot each, in turn.

100% packet loss when pinging the server doesn't actually tell us much. Be exact, please. Explain how you use:
* name resolution method?
* IP method?
* any router ports involved?
* which service ports are being used?
* which daemon?
* is the public IP static or dynamic?
* Did this ever work previously?

I set up a DHCP reserveration on my router. I think it is a dynamic IP address but it hasn't changed for months (even after restarting router). I did say I'm a nooblet and some of the terminology you're using I don't recognize so I can't answer them. How do you know the issue is not with the server networking for sure?
