Hello friends, i got a problem, that at our Node Red Server the mqtt out node doesn’t work any more since the update to 3.25.0 on Monday. The mqtt in node does still work. We use the mqtt out Topic: v3/XXX@ttn/devices/XXX/down/push Is there any one with the same problem? Thanks for help! ---

The Problem was, that the mqtt iot hub to ttn now works with base64 encoding. We changed the Payload to base64. Now it works again. ---
