I was trying to install rke on AWS ec2. I installed the server using:

./rke-install.sh --cloud-provider-name=aws

. I have tagged the node as well as checked the IAM policy. But my loadbalancer services remain stuck in Pending. Is there a way to check where the issue might be?

Check the cloud provider logs and read through the aws cloud provider docs. You need to configure a cluster name in the cloud provider config and put a matching tag on the subnets if you want to use load balancers
