Localhost problem


Hello, I have a problem with my localhost of 000webhost.com, I have a user account system through which I have to confirm the account once the registration is done. However, when I register and send confirmation token by email, localhost can not confirm. Here is the error message that is sent to me:

This site is inaccessible
localhost does not allow the connection.
Do a Google search on localhost Register accounts.


Wait, what is a 000webhost localhost?
Are you on localhost or on 000webhost?
