I don't see a crash here. Can you explain this in more detail? What do you mean with on reboot? Does monerod start correctly when you start it manually without systemd?

[jaredmo]

Crash may be the wrong word. The p2p error at the end is the problem. It only occurs with the options listed above in /etc/monerod.conf, and leaves the service in a failed state. I have the systemd service enabled so it starts automatically at boot. If I restart the service later (i.e. systemctl restart) it starts successfully with the listed options.

monerod works fine manually. The systemd service works fine as well without the options above. However, I would like to use them.

[selsta]

Can you add log-level=2 and share the logs? It currently doesn't show why it stops.

[jaredmo]

I figured it out. The service file wasn't waiting for networking to be online before starting. That's needed for DNS resolution using add-priority-node.

I changed the unit from network.target to network-online.target. Any chance of an upstream change?
