Server goes down after every few hours - No route to host

in flag

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!

Does `dmesg` shows anything unusual?

You say *hetzner console*, don't they have both a way to connect to your servers serial console, and a status indicator distinguishing "down" and "online" (just unresponsive)? Please [edit] your question to add the status determined through those methods, and the system log / journal lines the server recorded before becoming unresponsive.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
