**Issue:**  
Trying to register an ec2 instance to an elb. However, the ec2\_elb module doesn’t seem to work properly. It claims that the ec2 instance does not exist. However, when I manually registered the ec2 instance to the elb within aws console, then de-registered it, the ec2\_elb module worked and was able to find and register the ec2 instance. What is going on?

**Error:**
