I can SSH into my Oracle free VPS but after a while I find that the console is no longer working, and when I try to reconnect it doesn’t respond. I can still ping it, but even logging in to the website and trying to “Launch Cloud Shell Connection” doesn’t work, so it seems to be locking up completely after I SSH in, and I have to reboot it.

I’m only trying to use it as a reverse proxy with caddy, but it obviously needs to be reliable for that. There’s a few errors in the boot log, which I’ve pasted here, but I’m not sure if they’re important.

Oracle boot log - Pastebin.com

I’ve enabled Cockpit and the Services tab under that shows that kdump and SETroubleshoot failed to start. Should I just delete the instance and try creating a new one?

I followed this guide to setup the required rules for the VPS instance, and to create the iptables rules in the VPS, and to create the IPV4 and IPV6 A and AAA records on Cloudflare.

then I followed Steps 2 and 3 in this more recent guide to create the caddy files

but even before the VPS stops working the caddy server doesn’t serve anything when I try to access it in my browser.
