Cannot associate the Elastic IP address with a Network interface

0

I created an Elastic IP address, but when I am trying to associate the Elastic IP address with a Network interface, there was an error that says: "Elastic IP address could not be associated. Elastic IP address xx.xx.xx.xx: You do not have permission to access the specified resource.", although my AWS account has Administrator Access permission. There is a note that my subnets are public ones, is it an issue?

Another question, in order to convert a public subnet to a private subnet, do we only need to remove the Internet gateways from Route tables? Thanks in advance.

Hello.

Usually that error can occur if you don't have enough privileges to associate an Elastic IP.
Please make sure that the IAM policy described in the following document is attached to the IAM user you are using.

Yes, to make it a private subnet you need to remove the route to the internet gateway from your route table.

  • Thank you for your help. I tried to add the following policy to my user but it does not still work: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "ec2:AllocateAddress", "ec2:AssociateAddress" ], "Resource": "*" } ] }

    Any suggestion on this?

  • Which resource is the ENI you are trying to configure Elastic IP associated with? As @Kallu says, if your account is an unmanaged ENI, the configuration may fail.
