Failed to handle write to Metric Device Control/Rebirth

Hello all,

May I have some assistance narrowing down what is causing the following issue?
Failed to handle write to Metric Device Control/Rebirth

What version of MQTT Transmission are you using?

I am using version 4.0.7

I changed my MQTT broker to one that only I was connected to and I didn’t have any errors.

So - something appears to be writing to the ‘Device Control/Rebirth’ tag on the Engine/Host side. This is failing because that tag is no longer supported in MQTT Transmission. You should delete the ‘Device Control’ folder on the MQTT Engine side and do a Refresh on the Transmission side. This should make it so only valid tags are shown on the MQTT Engine side.

Thanks, I will test that out tonight.
