Logging via google account problem
I have a problem with logging in Duolingo via my google account. Everything seems to work fine except from the fact that Doulingo does not let me in. I just stay on homepage "unlogged". The user name and password is correct, because when i want to acces gmail (in the same browser) i do not have to log in. I have had this problem in chrome, but now i have it in all browsers (chrome, firefox, ie). I am behind corporate network/firewall. Does anyone know any tip that could help me to log in my original account?
