Amazon EC2 error while launching instances The maximum number of VPCs has been reached

I am trying to create a Python program using boto3 that creates an Amazon AutoScaling group. Define scale up and scale down policies and corresponding CloudWatch alarms. Supply the startup script created in previous step while launching a new instance from the program. Using a security group port 80 open,here is the program ,

how ever I have not reached that stage to write scale up and scale down policies for cloud watch alarms in the above code, it is just that while executing it before proceeding further I got following errors,

What should I do to get rid of this error :The maximum number of VPCs has been reached.
, I use free tier services of amazon.

I have 6 vpc all mentioning defalt logged in to web console don't know command line output to find themhere are they

the description of all of them reads Default VPC security group.Basically what I am trying to achieve is to create an auto-scaling configuration for the web tier of a cloud application. Following the steps below. Create a static website with one or two HTML pages and copy the pages and dependent files in an Amazon S3 bucket. Create a startup script to install Apache server and copy the website files from S3 to the instance. Create a Python program using boto that creates an Amazon AutoScaling group. Define scale up and scale down policies and corresponding CloudWatch alarms. Supply the startup script you created in previous step while launching a new instance from the program. Use a security group port 80 open. Open the public DNS of the newly launched instance in a browser and verify if the static website works.What I have not been able to do above is set cloudwatch alarms and metrics and see how they run in my code.
