Proxmox host stops responding, LXC continues (infosec.pub)

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?

It could be a failing drive. If you have a spare drive you could reinstall on there and import your guests. Could save hours of troubleshooting software ghosts.

    Thanks, I'll try that. Something odd is also happening where I just realised I can access it by tailscale, but not the local network so that narrows it down a bit, but I'll give the spare drive a go first.

    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

    There you go :) I’ve had a Pi running Tailscale and it ws not reachable using its local IP (it was accessible when using Tailscale IP) when Tailscale was started. When I was using Tailscale for site-to-site connectivity (subnet router) I ran it in an LXC container on PVE, so I’d advise you try that. Avoiding installation of additional software on the hypervisor seems like a smart idea - whenever I can I put stuff in containers/VMs.
