Since the last upgrade of The Things Stack Cloud to v 3.25.0 on April 3rd, I’ve been experiencing an issue with posting downlinks via MQTT. I am using the following topic for publishing downlinks:
I am also listening to the following topic to confirm successful downlinks:
I haven’t introduced any significant changes to the code, but it stopped receiving messages.
I’ve already spent a lot of time trying to fix this, without success. I even tried following an advice on a resolved issue, that I thought could be related.
