Is the MQTT server experiencing any problems?

Hi!
I'm having trouble sending data to a channel using MQTT. I'm using a program that was working perfectly until just a few days ago, but after making some minor changes yesterday, it stopped working. I’ve also tested it manually using the MQTTX client. If I send data using CURL and GET, it works fine.
It’s a bit strange...
Thankfully,
Ernesto.

Can you explain how this problem occurred?

Unplanned updates on the server instances fronting ThingSpeak's MQTT API caused some nodes in ThingSpeak's high-availability MQTT cluster to get into a bad state. These changes were unrelated to ThingSpeak application code, as evidenced by the REST API working faultlessly in @Ernesto's post. We worked with the platform provider to address the issue and have confirmed things are working correctly again for all clients of the MQTT API.

This issue has occurred again and has lasted for 30 minutes.

The additional monitoring we put in place didn't see any issues on any nodes. Did you see any effects on multiple devices? If so, can you please send me an email with the channel numbers?

Can you please try again. A subset of MQTT devices seems to have seen an issue publishing. We've restarted nodes in the system and can confirm things are back to 100% from our dashboards.

Also having issues. Have different location and devices. All stopped working basically about 24 hours ago. It is only those that publish on the mqtt server. The one that is on restful is working. Thanks Jacques
