Web Filter keeps blocking Anydesk Services

Hi,

Old Checkpoint R77.30 user, I'm using now one cluster of FG100E with v5.6.7 build1653.

I'm having difficulties with Anydesk: all my workstations can't connect to Anydesk's services (error ssl_14090086).

Application Control is on with "Monitor all applications" default profile and no trace of Anydesk in Application Control Log

But in Web Filtering logs, it's full of  hostname "AnyNet Relay" or URL "AnyNet Relay/" sometimes with non resolved IP or the classic boot-*.net.anydesk.com or relay-*.net.anydesk.com with Unrated Categorie.

I've added Static URL Filter but no success. I can't add wildcard * expression in Web rating Overrides.

I've also made a rule for testing with any any all "Anydesk-Web" but this Internet Service have only 28 entries and i can't edit thoses.

The only thing that works: remove the Web filtering, and i don't want that.

If someone could give me some hints. 

Thanks.
