I changed the server from hostname to IP address and did not resolve. I also changed the topic name from coop, to either /coop, coop/solar, and /coop/solar, and also could not resolve. There are over 10 different devices that are publishing to the same MQTT server without issue.
Version: 5.0-0dc546-2023-01-22-20-34
Update Channel: Stable
Hardware: v4 w/external WiFi antenna (2021)
Here is the log snippet where the failure starts:
Code: Select all
