Captcha validation issue

Our application is currently using recaptcha in production and working fine 
without any issues. 
I am working on moving the application to another data center and the same code 
base (same private key) is giving me an exception as attached. The exception is 
thrown by method below:

final ReCaptchaResponse reCaptchaResponse =
      reCaptcha.checkAnswer(remoteAddress, challenge, response);

The remoteAddress being passed is 10.137.7.20-29  and other paramaters are just 
the same as in current data center.

What is the expected output? What do you see instead?
Captcha should get validated. But, it triggers an exception
