MQTT subscription via Nodered connected but no data

25 views (last 30 days)
I have MQTT subscription to my channels for a long time. Everything worked till Friday May 12th, 2023 at time approx. 18:16 UTC. From that moment MQTT nodes in Nodered have status Connected, but no data are coming in via MQTT. My data are uploaded to Thingspeak regulary and visible in my channels. There were no changes to my settings at that time. Any idea what has changed ?

Hi,
Just adding that I am seeing this as well. I was working on the server side of my application today ( not the code that connects though) when I noticed no data coming in from Thingspeak. Data is getting to my channel from my sensor, and my application subscribes without error, but then silence; no data moving from Thingspeak to the channel. Last data from the channel was sent around 6 pm GMT May 12, 2023.

The MQTT subscription service was purged and restarted today just after 1 p.m, and is now working as expected. No messages sent to ThingSpeak have been lost, but MQTT devices did not get messages from channels they were subscribed to since Friday, May 12. While this is consistent with the QoS 0 policy, we expect the service to return to normal now and maintain its historically high uptime.
If you continue to see missing subscription messages, please let us know here.

We had a reset of the system on Friday. Can you please try again and let us know if you are still having this issue today?
