IPv6 only server unable to connect postman.com or getpostman.com

Hi,

I have a IPv6 server and unable to access https://postman.com/ or https://getpostman.com/, it will not redirect to www. However, if I use www-postman-com or www-getpostman-com has no issue. Any problem with IPv6 backend?

Note: I can manually using www but the Postman APP using postman-com and get postman-com by default without www and failed to redirect and connect.

Error:

This site can’t be reached

The connection was reset.

Try:

Checking the connection

Checking the proxy and the firewall

ERR_CONNECTION_RESET

curl -4 -v https://-postman-com
