This might be caused by a misconfiguration. The related file
/etc/icinga/apache2.conf contains a stanza "Require all granted"; it is
a copy of /usr/share/icinga/apache2.conf, belonging to the icinga
package. Try to access https://www/icinga after having commented this
line in /etc/icinga/apache2.conf and restarted Apache.
