I have a leagoo lead3 running android 4.4 and after factory resetting it I'm no able to add my google account.
The error I receive is "Couldn't sign in" " There was a problem comminicating with Google servers. Try again later."
Googling I find that hosts file in /system/etc needed to be modified to comment out "xxx.xxx.xxx.xxx android.clients.Google.com" but I don't have this line.
Also I checked http traffic with fiddler and I just have this :
"200 HTTP Tunnel to 18.104.22.168:443" with body 0
It seems to be a good google ip. I don't what to check now... Any help will be appreciated.
