Woke up this morning to ALL of my sensors being unavailable. HA log shows a lot of “connection refused” errors.
One of many:
“2020-09-05 10:40:25 ERROR (MainThread) [homeassistant.components.plex] Plex server (http://172.30.33.12:32400) could not be reached: [HTTPConnectionPool(host=‘172.30.33.12’, port=32400): Max retries exceeded with url: / (Caused by NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x7fc3d427d760>: Failed to establish a new connection: [Errno 111] Connection refused’))]”
and half a page of this:
2020-09-05 10:34:39 WARNING (MainThread) [homeassistant.components.cloud.google_config] Error reporting state - message_discarded: Message discarded because max messages reachced
Here is the kicker. I rolled back to a back up from 2 days ago when everything was fine, and it still does it.
