Socialite on Google App Engine

I have managed to port most of my app to Google App Engine. I'm using shpasser gae for laravel 5. My issue is with Socialite and I believe it is related to Curl or ssl. My code works locally and in production (not on google app engine) I have the curl.so extension registered in my php.ini file. I am getting a curl error number 7
