Google Hangouts gives "Can't sign in because we couldn't reach Google. Try again" error I have updated and replaced Google Talk with Hangouts on my tablet running Cyanogenmod 10.1. Now every time I open the Hangouts app it shows me the following error message:


  Can't sign in because we couldn't reach Google. Try again


How can I fix this?
Re-installing the 'Google Play Services' updates solved the problem for me.

Simply go to Manage Apps &rarr; Google Play Services and press Uninstall Updates. Now if you start Google Hangouts again it will ask you to update Google Play Services. If you do so, it will bring up Google Play where you can install the update.

After this, Google Hangouts started without any problems on my tablet.
