Problems detaching ENIs?

Confused?

One might come across certain issues when trying to manually detach the Network Interfaces. Some sample errors:

• eni-xxxxxxx: You do not have permission to access the specified resource.
• “Error detaching network interface. eni-xxxxxxxx: You are not allowed to manage ‘ela-attach’ attachments.”
• Network interface ‘eni-xxxxxxxx’ is currently in use.”

Solution:

1. Navigate to Network Interfaces in the EC2 console.
2. Select the ENI and open the Details tab.
3. Review the Description to find which resource the elastic network interface is attached to.
4. Consider deleting the described service if not being used. (ENI will automatically be deleted if the service is deleted).
