[Solved] Why Hetzner Ubuntu Server keep going down – No route to host

Awaish Kumar Asks: Why Hetzner Ubuntu Server keep going down – No route to host
I have a ubuntu machine, it keep going down after some(10-15) hours. it returns the error as no route to host when I try to ssh. But it works when I restart from hetzner console and again after few hours it goes down.

I checked:

  1. syslogs: there are lots of ips trying to connect to machine but are being blocked by firewall (ufw).
  2. I checked auth.log but I could not find any suspicious login.
  3. I checked CPU utilization over time but that’s also fine.

But now I don’t have any clue what to look for, Any help would be really appreciated!
