FTM push responses not working (dns problem ?)

Hi,

I'm trying to setup the FTM with FortiToken Cloud.

• User login in FortiClient IPsec VPN
• FortiGate sends push request to my phone
• Tapping Allow 
• Getting notification on my phone “request sent”
• And nothing happen

fortigate debug:

dns_parse_resp: eufctupdate.fortinet.net: rcode=3

FortiGate can't resolve the hostname? 

Latest version: v7.6.6

What i'm missing here ?

Regards!
