Web filtering is not working as expected

Hi, i've already exempted the url hsselite.com from webfiltering as in the attachment image.

i've tried with both regular expression with "api.hsselite.com" and wit wildcard "*hsselite.com", but i'm recieving this alert email from fortigate:

Message meets Alert condition

Now i don't really know if i've setup a wrong config.

Please is everyone that can support and tell me why fortigate is blocking this website?

Thank you very much for support.
