Proxmox 6 rebooting on Hetzner server

[fellow1033]

Having huge issues with Proxmox on Hetzner server(i9 9900k, 64gb, 2x 1TB NVME).

Server seems to be rebooting randomly, checked syslog, but looks like it is start at a time of restart:

It is a default Promox 6 iso, default settings, just setup bunch of VM/CT (I am using similar setup on other Proxmox 5.x and working just fine).

Ask Hetzner, may be a hardware fault.

There was a problem with a network driver we also had in a hetzner setup, maybe this is also your problem?

Hi all.
The same issue here
Two servers with Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz goes into reboot suddenly.
In the proxmox panel I see same message in the syslog section:
Oct 20 20:12:01 node1 systemd[1]: Started Proxmox VE replication runner.
-- Reboot --
Oct 20 20:13:37 node1 kernel: microcode: microcode updated early to revision 0xae, date = 2019-02-14

We're trying to fix it by
1. kernel update
2. hardware replace
And with no luck

Btw we have this controller: Intel Corporation Ethernet Connection (7) I219-LM (rev 10)
