You need to provide more details for anyone to be able to help. But please do read the FAQ about "your own code"

Are you sure the IRMQTTServer is connected/connecting to an MQTT server correctly?
What does the (entire) /info page have to say?

e.g.

Thanks for you dear，I found the cause of the problem：“Buffer Size: 768 bytes”, Becuase the JSON Message Large than 768Byte, Change to 1024,everything is OK! My English is poor. haha!
