fetching emails without login on OSticket

Hi,

Looking for solution where OSticket server will fetch the emails and convert them into the ticket without even login on osticket admin page. My email fetching is working fine when I'm logged on web Admin panel.

Server Details;
OS: - Ubuntu 16.04 LTS
OSTicket version : - v1.10 (901e5ea)
Web Server Software: -    Apache/2.4.18 (Ubuntu)
MySQL Version: -  5.7.18
PHP Version: -  5.6.30-11+deb.sury.org~xenial+3

Crontab entry;
*/3 * * * * /usr/bin/php -q /var/www/html/api/cron.php
This didn't worked for automated fetching the mails w/o login, so added another entry;
*/3 * * * * wget -q -O /dev/null --user-agent=<55B5EC2ADC1EB81C4AA0ABAREMEOS> http://mywebsitename.com/api/cron.php


Not sure what i'm missing, please help me.

Thanks in advance.
