But when I log in osticket, the fetch works.
Is tgis normal? Is it still cron issue?
That's because it's using Auto-cron which is a crutch really. Yes, still means cron job isn't working properly. As I mentioned above: Contact your hosting provider for the correct PHP path to use.
Do you know what command needs to be set in cron?
It's typically:
php /path/to/osticket/api/cron.php
However as I said above you are using a hosting provider and each provider has their own specific setup. You need to contact your host for further assistance.
Cheers.
