XG-7100 AWS VPC Wizard Error - "Error occurred for request of type :" ... "Region Selection"

[nu2pfsense]

Just received our new XG-7100 and have been looking to connect it to an AWS VPC using the provided wizard: https://docs.netgate.com/pfsense/en/latest/solutions/aws-vpn-appliance/vpc-wizard-guide.html

However, the initial configuration page does not include an option to select the AWS region as shown in the documentation (see attached screenshot - removed Access Key ID):

In addition, if I proceed to enter the administrator IAM user credentials and click Next, it results in this error:
"Error occurred for request of type :" ... "Region Selection" (see attached screenshot - removed Access Key ID):

Questions:

1. How do I resolve this issue?
2. What are the minimum set of permissions required for the IAM user? AmazonVPCFullAccess + AmazonEC2FullAccess? (I was unable to find any documentation or forum posts that specify.)

Current Base System: 2.4.4_3
XG-7100 running behind an ASUS router for testing, configured with static private IP address 10.0.20.1 on WAN port with LAN address 172.16.0.1.

Thank you in advance!

If you enter valid keys there it should ask you to select the region on the next step.

@stephenw10 Thank you for taking a look!

After further investigation, this was due to a misconfigured WAN interface on the XG-7100 that prevented internet access (see Unable to ping to/from netgate XG-7100 WAN interface for details). The AWS VPC Wizard worked after fixing that.
