Can't access Elastic Beanstalk configuration page


For one of my environments, I receive the following error:

A problem occurred while loading your page: Configuration validation exception: Invalid option specification (Namespace: 'aws:autoscaling:launchconfiguration', OptionName: 'InstanceType'): Your selected instance types (t1.micro) aren't available in your selected VPC Subnets. t1.micro is available in [us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1f]. Please check your VPC Subnets.

Does anyone know how I can change the subnet when I can't access the page to do so?

The docs call out the following...

"The InstanceType option is obsolete. It's replaced by the newer and more powerful InstanceTypes option in the aws:ec2:instances namespace. You can use this new option to specify a list of one or more instance types for your environment. The first value on that list is equivalent to the value of the InstanceType option that's included in the aws:autoscaling:launchconfiguration namespace that's described here."

"The instance types that are available depend on the Availability Zones and Region used. If you choose a subnet, the Availability Zone that contains that subnet determines the available instance types."

Consider updating the configuration through the EB CLI. Refer to
