Accessing site using IPv6

Hi all,

HTTPS connections to cndstatic.ventusky.com using IPv6 are timing out. Is this a known issue?
Attached image shows the successful SSL handshake when using IPv4. But the IPv6 attempt hangs at the "Connected" stage.

Thank you for your report. We’ve made some changes to the server settings. Please try it again.

Doesn't appear to have had any effect.

On our side, everything appears to be in order according to the available tests: https://ready.chair6.net/?url=cdnstatic.ventusky.c...

Thank you for checking. I am inclined to agree with you that everything is in order on your side. As per the below I am having similar behaviour with xbox.com. They serve some of their static via the same edge as ventusky.

Now to figure out if it is my home network or not.

Right, worked out what the issue was. My connection to my ISP was using 1492 for the MTU. I've changed this to 1500 and we are cooking with gas.
