MQTT Gateway Configuration with Temp Sensor not working

Hi, I am trying to connect sensor to MQTT gateway.
Solutions tried:
-Resetting the Gateway
-Tried with multiple sensors
-Sensors I have tried, are working fine with other MQTT Gateway
-Gateway is connecting fine with broker and showing the sensors but the only issue is its not configuring them and showing the failure status as shown in pic below.

This gateway was working fine before and sensors were connected to it, but suddenly started having issue. Can it be a hardware issue?

I doubt it’s hardware related.

What browser are you using? If it’s a Microsoft browser try using Google Chrome.

If you are using Google Chrome then you could try updating the firmware in the gateway by following these instructions:

Thank you,
