MC Server Doesn't Ping But Websites Do.

[Nrevi]

So,

I'm encountering an issue on my vps hosted by OVH. A server is running yet I can't even connect/ping to it. My websites run perfectly fine, it's just the server that is not pinging. Yesterday and the day before it was all fine, it only started today. If someone could help me out here, I'd very much appreciate it.
