I reset my Dragino Temp and Humidity device, but it will not show up.

I am having trouble getting my LSN50 Temp/ Humidity sensor to work. it has been 5 months since the last reading. I reset the device, but it still won't register with Tago. I have the same Dragino Gateway connected. If I haven't touched or monitored this in five months, I was hoping that it would begin to read again. There is a screenshot below. 
        Take a look at our updated roadmap here!
          What would you like to see on TagoIO?
