Description of problem:
Create VPC and subnets with following configs [refer to attached CF template]:
Subnets (subnets-pair-default) in CIDR 10.0.0.0/16
Subnets (subnets-pair-134) in CIDR 10.134.0.0/16
Subnets (subnets-pair-190) in CIDR 10.190.0.0/16
Create cluster into subnets-pair-134, the bootstrap process fails [see attached log-bundle logs]:

Checking security groups:
<infraid>-lb allows 10.0.0.0/16:6443 and 10.0.0.0/16:22623
<infraid>-apiserver-lb allows 10.0.0.0/16:6443 and 10.134.0.0/16:22623 (and 0.0.0.0/0:6443)
are these settings correct?
Version-Release number of selected component (if applicable):
4.16.0-0.nightly-2024-06-03-060250
How reproducible:
Always
Steps to Reproduce:
1. Create subnets using attached CG template
2. Create cluster into subnets which CIDR is 10.134.0.0/16
3.
Actual results:
Bootstrap process fails.
Expected results:
Bootstrap succeeds.
Additional info:
No issues if creating cluster into subnets-pair-default (10.0.0.0/16)
No issues if only one CIDR in VPC, e.g. set VpcCidr to 10.134.0.0/16 in https://github.com/openshift/installer/blob/master/upi/aws/cloudformation/01_vpc.yaml
