At the Rails 4 project, I use google oauth2 access in authentication. I
All do well in PC’s browser. But when new user register with google at
the mobile phone’s browser, omniauth callback failure error is occured
and frozen at google allow access page. If new user did registration at
PC, mobile phone can login successfully. Just only faced with frozen
error when new user register with mobile phone. I used both Android and
IOS phone, but both face same error.
