With 23.1, on the Dashboard, the widget for Telemetry Status for ET Telemetry just shows a spinning circle. The first time I noticed, I removed the widget and added it back, which seemed to resolve it. However, a few minutes later, back to the spinning circle.
Thanks.
Update -- this seems to relate to issues with Unbound DNS. Because of not being able to check email (Comcast), I have moved back from Unbound to using a separate Pi.Hole DNS server, and this appears to resolve the issue with the telemetry gadget not showing correctly.
