Change

curl_setopt($curl, CURLOPT_SSLVERSION, 3);

to 

 //curl_setopt($curl, CURLOPT_SSLVERSION, 3);

from curl.php according to github.com/google/google-api-php-client/issues/639 and now working fine

When the user clicks authenticate you are given an authentication code. You take this code and exchange it for your access token and refresh token.

'invalid_grant: Code was already redeemed

Means that you are taking an authentication code that has already been used and trying to get another access token / refresh token for it.

If it has worked for the last 4 months my opinion is that someone changed something in your code and broke it.
