Xampp - localhost not working - apache

Question

Although apache seems as "working" on xampp control panel,I can't reach the localhost or 127.0.0.1 . I changed 80 port to 81 but not solved.
httpd.cong -> Listen 0.0.0.0:80
My host file in system32/drivers/etc directory is like
127.0.0.1 localhost
Last log in the apache error log is

Answer 1

Sometimes the port 80 is used by other applications on windows such as skype.
Try changing the ports to 8080 in the apache>config>httpd.conf
and to 4433 in the apache>config>httpd-ssl.conf
Sometimes your network maybe creating an issue. Try disconnecting the network and reloading the localhost. If it works, then its your network restrictions.
