Hi @magefister I think this is related to two things:

• the Nginx image used by the webapp listens on ipv6 by default
• Your Kubernetes cluster does not use ipv6 ? (maybe because your Kubernetes version is too old?)

This issue is more related to the nginx image than to Airbyte according to this one nginxinc/docker-nginx#394. But nginxinc/docker-nginx#394 is closed so maybe upgrading our Nginx image to a more recent version would fix this problem?

airbyte does have ipv6 enabled in the default template however: https://github.com/airbytehq/airbyte/blob/master/airbyte-webapp/nginx/default.conf.template
