The error message you're encountering is related to your AWS account's vCPU limit, which is currently set to 1. This limit is in place to protect users, especially those on the Free Tier, from unintentionally incurring costs by running multiple instances.
To resolve this issue, you have a few options:
-
Request a quota increase: You can request an increase in your vCPU limit by visiting the AWS Service Quotas console. Navigate to the Amazon EC2 section and look for the quota related to the instance type you're trying to launch. You can then request an increase for that specific instance type.
-
Use a different instance type: If you're on the Free Tier, you might be limited to certain instance types. Try launching a different instance type that might have a separate quota.
-
Check running instances: Even though you've confirmed that other EC2 instances are terminated, double-check your EC2 dashboard to ensure no instances are running or in a stopping state, as they might still be consuming your vCPU quota.
-
Consider region-specific limits: vCPU limits can be region-specific. If you're trying to launch instances in different regions, make sure you're not hitting the limit in a specific region.
-
Wait and retry: In some cases, there might be a delay in freeing up resources after terminating instances. Wait for a short while and try launching your instances again.
If you've verified all the above and still face issues, it's recommended to contact AWS Support for further assistance. They can provide more detailed information about your account's specific limitations and help you resolve the issue.
Remember, while on the Free Tier, you're generally limited in the number and types of instances you can run simultaneously. Always be aware of these limitations to avoid unexpected charges.

You may still have an existing EC2 instance running. Is this a M instance type?
Go to Service Quota console for EC2 at https://console.aws.amazon.com/servicequotas/home/services/ec2/quotas (Select the correct Region). Search for Running On
, and check your Utilization
against Applied account-level quota value
For M instance, click on Running On-Demand Standard (A, C, D, H, I, M, R, T, Z) instances
, and use Request increase at account level
to request higher limit. Link is at https://console.aws.amazon.com/servicequotas/home/services/ec2/quotas/L-1216C47A
Hello.
To addressing the vCPU limit issue in your AWS account Please follow the below steps.
Request a Quota Increase
- Go to the AWS Service Quotas console.
- Navigate to the Amazon EC2 section.
- Find the quota related to vCPUs for the instance type you want to launch.
- Request an increase for that specific quota.
Use a Different Instance Type
- If you're on the Free Tier, you may be limited to specific instance types.
- Try launching a smaller instance type that falls within the Free Tier limits (EX. t2.micro or t3.micro).
Check for Running Instances
- The EC2 dashboard to ensure there are no running or stopping instances that might still be consuming your vCPU quota.
Consider Region-Specific Limits
- Remember that vCPU limits can vary by region. If you’re trying to launch instances in different regions, make sure you haven’t hit the limit in that specific region.
Retry
- If you've just terminated instances, there may be a delay in resource availability. Wait a few minutes and then attempt to launch your instance again.
