I have installed the Advanced google reCAPTCHA plugin ver2 to my domain "aquilbiz.com" and it is working but login out from my wordpress dashboard and tried to login it does not work. And this is happening again and again for the last 2 weeks or so. 

I have also contacted my servive provider for the purpose and they make it error free and both my website dashboard and cPanel dashboard worked. I reconfigured the secret key and the other key, but after login out and then login again the links for both the wordpress dashboard and cPanel did not opened.

I have tried edge, chrome and firefox browsers after clearing the history of these browsers but the results are the same as attached here attached here. 

I have also applied DOS commands such as ipconfig /flushdns, etc., but the result is the same

Somebody please help

Regards,

Aquil
