See if you are able to access/list the ‘/icons/’ directory. This is useful to test the behavior of “Directory” in Apache.
For example: You might be having the below configuration by default in your httpd.conf file. So hit the URL IP:Port/icons/ and see if it lists the icons or not. You can also try by putting the ‘directory/folder’ inside the ‘var/www/icons’.
Alias /icons/ "/var/www/icons/"
<Directory "/var/www/icons">
Options Indexes MultiViews
AllowOverride None
Require all granted
</Directory>
If it does work, then you can cross-check or modify your custom directory configuration with the ‘<Directory “/var/www/icons”>’ configuration.
