Why can’t my account create a Lightsail instance

There are a few potential reasons why you may be unable to create a Lightsail instance:

1. Account limitations: New AWS accounts often start with lower quotas than the default limits. Even if your account shows a quota of 20 instances, the actual limit may be lower. This is especially common for very new accounts (1-2 days old) while they are being fully initialized and billing methods are validated.

2. Hidden quota restrictions: Sometimes there can be hidden quota restrictions that prevent instance creation even when the displayed quota limit has not been reached.

3. Insufficient capacity: AWS may not have enough available capacity in the selected region/availability zone to fulfill your request at that moment.

To resolve this issue, you can try the following:

1. Try creating an instance with a smaller plan size. The error message suggests that smaller plan sizes might be available to you.
2. Wait a few minutes and try again, as instance capacity can shift frequently.
3. Try creating the instance in a different availability zone or region.
4. If creating multiple instances, try reducing the number in your request.
5. Submit a limit increase request through Service Quotas:
   • Navigate to the Service Quotas console
   • Search for "Lightsail"
   • Select the quota you want to increase
   • Choose "Request quota increase"
   • Fill out the request form with your desired limit and business justification

If these steps don't resolve the issue, it's recommended to open a support case with AWS under the "Account and billing" category. This can typically be done free of charge and may be necessary to adjust any hidden account limitations.
