How can I configure my VPC security group to allow access out to one of our AWS Cognito endpoints?
The endpoint is of the format https://cognito-idp.eu-west-2.amazonaws.com/<poolId>. This currently resolves to IPs 3.10.197.95 and 3.10.250.171 for example (probably tonnes more).
I'm aware of the published AWS IP ranges, but Cognito doesn't appear to be a supported service there. I also can't find the 3.10.x.x addresses above in the published list.
Thanks
