Your device has probably set wrong date and time, which somehow affect the connection to SSL secured server. The solution is to set the correct date & time.

1. Connect to your device via SSH (see ssh)
2. Check if the date is incorrectly set

   $ date

3. If not, update it (e.g. use UTC time from http://currentmillis.com)

   $ date -s "2017-12-11 12:00:00"
   $ hwclock --systohc
   $ reboot

Try to setup the account, it should work fine now.
