Expiry of SSL certificate

Tailscale version 1.42.0
Your operating system & version: Ubuntu 22.04.2

I have been recently notified by a number of my devices and web browser that my SSL certs for one of my tailscale instances have expired.

Is the the tailscale implementation of Let’s Encrypt not setup to auto renew? Is it not setup to notify me of expiry, like Acme does? Do I have to manually renew my certs?

Thanks.

Well, since no one replied to this, I manually renewed it. Bit of a PITA, but everything is working again.
