Problem Www Non Www

I changed the store's name (admin panel / administration / stores) from example.com to www.example.com and I noticed the following problem; the store is displayed correctly when I type www.example.com in browser, but when I type example.com appears unavailable service.

I appreciate your help.





Thank you,
