HELP! One Host of cluster not reachable after reboot

[prahn]

Hi!

I have a Proxmox cluster with 3 hosts and CEPH running, I did all the recent updates, but did not reboot them for a while now.
However, I did a reboot of the first host right now, the reboot ran fine, but after the host is back up, it is not reachable in the network?!
Any idea, what this could be?

I did a second reboot, hoping that this will solve it, but this did not help.
In the Proxmox WebGUI I see that the host is back online (green tick), but when trying to access it I get "Connection error 595: No route to host".
When going on the console and execute "ifconfig" I see the interface all setup correctly...
But from here, I can also not ping any machine on the network?!

Also the CEPH network is down and says "Degraded".

PLEASE HELP!
Thank you.

After searching the forum now, I read something about network problems with new kernels...
So I did another reboot and choose the kernel to version 6.5.13-1-pve while booting, the version that is also running on the other two hosts.
Finally the host is back to network and running fine!

But how to deal with this now?
Do I have to stay with this old kernel now forever?
Could I add support for my network cards to the new kernels?

Regards,
Prahn
