Hi Zhiyi

It seems that the CA is still offline.
systemd should automatically restart the service when it crashes, but it’s
not working properly. Please check your unit file.

In case it’s a prefix announcement problem: run the registration command
via crontab or systemd, not in a console window.

Yours, Junxiao
