tgibbs99 on Thingspeak and Wemos D1 Mini

I have been trying to use the Arduino IDE examples posted on GitHub, with Wemos D1 Mini.  I am using the ReadPrivateChannel example.  The code compiles and I get no error messages.  However, the data returned is always either "0.00" or null.  I am posting data to thingspeak using other code, I am not able to get the WriteVoltage Example to work either. 

Does anyone know why this does not work with Wemos D1 mini? Is there a work around?

Thanks.
