How to recycle aws server app pool remotely

I am trying to recycle the aws app pool remotely using below syntax

using (DirectoryEntry appPoolEntry = new DirectoryEntry(
    "IIS://" + appPoolModel.ServerName + "/W3SVC/AppPools/"+appPoolModel.AppPoolName))
{
    appPoolEntry.Invoke("Recycle", null);
    appPoolEntry.Close();
}

But i am getting this below error

System.Runtime.InteropServices.COMException (0x800706BA): The RPC server is unavailable.

For aws server i am using the server name as follows

"ec2-[Server Public IP].compute-1.amazonaws.com"
