All of my network interfaces have disappeared except for my loopback address. All of my physical interfaces, virtual interfaces are all gone. ifconfig only reports back loopback (lo), ifconfig -a reports back loopback (lo) and ethernet (enp1s0f0)
All I did leading up to this was backup my iptables rules iptables-save > backup.txt, flushed iptables (had to for debugging purposes to rule something out) iptables -F, restored with iptables-restore > backup.txt, rebooted, all my network interfaces are gone, which basically means my server can't contact or be contacted by any other devices in my network.
I have zero clue how to fix this, I've been trying at this for hours with absolutely zero luck. I'm this close to just reinstalling from scratch because I'm almost positive I could spin up a new server with all of my services installed in less time than I'll spend debugging this and pounding my keyboard for hours on end. I don't know why my temporarily backing up and restoring iptables deleted all of my interfaces. I tried searching for anything like this having happened before and I couldn't find anything even remotely similar to what's happened to me here.
