Our update has been rejected twice today for ipv6 network connectivity issues. Our networking code has not changed between the previous release and this current release.

The app only makes https network requests to api.metooapp.io, which is correctly configured for ipv6 [0] and runs behind route53 on AWS. There are no hard-coded IP addresses in the code.

I am unable to reproduce this issue, even after following the steps to create an ipv6 network at [1] which is the link that was provided in the rejection notice. It looks like I'm not the only one experiencing this issue, either [2].

After quite a bit of stress, I can confirm that the issue was a problem with our backend not being correctly configured for IPv6. Apparently, AWS doesn't support IPv6, nor IPv6-only DNS through Route53. I ended up moving all the internet facing bits of the backend away from AWS for the time being.

I wanted to leave this up because I think there are probably going to be others who find themselves with similar problems as people start submitting updates past the IPv6-only restriction. The best tool I found for testing server/dns readiness has been: http://ready.chair6.net/
