Upstash Redis Connection Lost

1

One of my 3 production server instances has lost connection to the Fly Upstash Redis host?

The other 2 instances seem to have a stable connection. Any thoughts?

Restarting the machine manually seems to have gotten the connection back online. Is there anyway to debug what caused this?
