Error Codes
Topics
Overview
There are two types of error codes: client and server.
Client error codes suggest that the error was caused by something the client did, such as an authentication failure or an invalid AMI identifier. In the Query API, these errors are accompanied by a 400-series HTTP response code.
Server error codes suggest a server-side issue caused the error and should be reported. In the Query API, these errors are accompanied by a 500-series HTTP response code.
Summary of Client Error Codes
| Error Code | Description | Notes |
|---|---|---|
AddressLimitExceeded
| You've reached the limit on the number of elastic IP addresses your account can have. |
Each AWS account has an EC2 elastic IP address limit. For new accounts, this limit is 5. If you need more than 5 EC2 elastic IP addresses, please complete the Amazon EC2 Elastic IP Address Request Form. We will ask you to think through your use case and help us understand your need for additional addresses. You have a separate limit for VPC elastic IP addresses (5). To request to increase the limit, complete the Amazon VPC Limits form. |

</Response>Eventual Consistency
The Amazon EC2 API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that when you run an API command, the result may not be immediately visible to subsequent API commands, which can result in an error.
For more information about eventual consistency and how to manage it, see Eventual Consistency.
