Ok well lets try this. Go to /etc then open the file called 'hosts'. It should look something like this:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
Heres what it should look like when you put the server in, this is also the server I use:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
5.196.242.73 game.clashofclans.com
After this, reboot your iDevice. If it still doesn't work, then they patched something
If they are down in general, CoC should be stuck on loading, not kicking you to the main server
