I’m running Proxmox 9 on a server with currently a single LXC running. On no apparent time schedule, within a day but frequently within an hour, the host will stop responding to SSH, pings and the web UI stops updating. However, the LXC continues to run happily. The only way to bring the host back up is to power cycle the server.
Has anyone got any troubleshooting tips?


Hmm, are you running Tailscale on the Proxmox VE, not in a container/VM?
I’m running it on both the host and the container
