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

[snobs]

Hello,

https://www.degen.solutions/ 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?

Regards

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.

--SNIP--

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

FWIW ssllab does not show this site as ipv6 nor does the ipv6 test
