Hi am have a test website “inside” of main site, and I trying to login with google and looks like works but later you choosed account you are redirected to main site and 404 error (or something like that).
facebook login works fine, I think is somethin google URI related but I dont have idea.
I follow documentations instructions but doesn’t work, please gimme a hand, see picture attached, thanks you.
The problem seems to be caused by your hosting server. Google redirects you to the page sending some serialized data via GET parameter in the URL. The problem that your server can’t parse it and it has some limitation on the number of characters in this parameter. Try to contact your hosting providers to increase it in two or three times.
