Here's the instruction to fix the SSH Connection problem;

AT THE COMMAND LINE IN A TERMINAL WINDOW:
sudo su 
raspi-config 

1) Choose first 'update'

2) In advanced options -> expand_root file system

3) interfacing options -> ssh [enable]

4) change_locale [your country-UTF8] and if you still here, it's good to change the timezone as well

5) change the default password (just do it and write it down somewhere..)
