Issue Server went down

[Bogdan1]

Hello,

I have a problem, today at 3AM(CEST) server went down and I can't even ping it.
Provider(OVH) said that problem is on my side(I haven't touched anything in Plesk for at least a month).

I can access VPS in rescue mode, but I have no idea what could be wrong and what should I look for.

I can ping server in rescue mode

Anyone had the same problem?
