I am currently working on a small php library that will allow users to access data from the Google Play Developer Console and paste it into the database for future use.
To achieve this, I authenticate with the appropriate Google service with GET and POST requests (this part is still fine), and then do various POST requests to get all the data I need.
Everything worked fine, I used the script myself (to get JSON responses) from 2 or 3 weeks, and I have been running it daily since: no problem.
Today I tried to run it again, and as a JSON response for any POST request, I get the following:

, , . Google ?
, - , , .
, ( ) 0, , .
Google , , .
