Does not reconnect to tailnet after network downtime

[aredridel]

I had an outage today, and my caddy service went awol, the ephemeral services expiring, even after the outage ended. I had to restart the server to get it working again.

Nothing interesting in the log but there might be a condition to monitor here.

what kind of outage was it? Like, lost upstream network connection? Anything on the machine running caddy itself? It's curious that #99 also reported issues during an outage, so I'm wondering if some recent change broke something, or if the timing is just coincidental.

Yeah, upstream broke, two hops away. It was down for about 12 hours. The actual local machine running tailscale stayed running the whole time, and the router kept handing out DHCP leases so IPs didn't change, but there was no connectivity.
