[Ubuntu]Apache says “Forbidden You don’t have permission to access this resource.” to a specific domain

Open the apache2.conf file using the nano editor.

sudo nano /etc/apache2/apache2.conf

Replace the general directory settings with this.

<Directory />
    #Options FollowSymLinks
        Options Indexes FollowSymLinks Includes ExecCGI
    AllowOverride All
        Order deny,allow
        Require all granted
</Directory><Directory /usr/share>
    AllowOverride None
    Require all granted
</Directory><Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>
#<Directory /srv/>
#   Options Indexes FollowSymLinks
#   AllowOverride None
#   Require all granted
#</Directory>

Ensure your virtual host configuration file in /etc/apache2/sites-available directory is in this manner

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port t$
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName example.com (put your domain name here)        ServerAdmin webmaster@localhost
        DocumentRoot /home/username/myapp (put your app root directory here)        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost># vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Restart Apache2 service

sudo systemctl restart apache2

That’s all.
