IPv6+TLS1.3: HTTPS website doesn´t load?

Hello, uses TLS 1.3. When I try to access this homepage the browser shows a white page, only. Disabling IPv6 one my client, the homepage loads without any problem.


I am running FortiOS 6.0.5. I already entered a new outgoing IPv6 rule for this single homepage without any IPS/webfilter enabled. Unfortunately the homepage still doesn´t load.


Has anyone a solution for this? Is there any known problem?

Hey snobs,


I don't know if this is a firewall issue. It seems that the site doesn't have an associated AAAA record. It has a CNAME but the linked CNAME also doesn't have a AAAA record.

Is the site reachable over IPv6 when not behind the FortiGate?
