From `httpd -v`, I get the below:

```
 Server version: Apache/2.4.16 (Unix)
 Server built:   Aug 22 2015 16:51:57

```

 Also, `etc/hosts` is as follows:

```
    ##
    # 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 
    fe80::1%lo0 localhost

```

I start the server using `sudo apachectl start` and it returns no error. However, I am not able to connect to `localhost` on a web browser. Would you suggest a solution? Thanks for your time.
