Hi,

I found the state of ec2 is not matched with actual, when I entered below codes.

import boto3
rsc = boto3.resource('ec2')
a = list(rsc.instance.filter(Filters=[{'Name': 'tag:Name', 'Values': ['my_ec2_instance']}]))
a[0].state
{'Name': 'stopped', 'Code': 80}
a[0].start()
a[0].wait_until_running()
a[0].state
{'Name': 'running', 'Code': 16}
a[0].stop()
a[0].state
{'Name': 'stopping', 'Code': 64}
a[0].wait_until_stopped()
(When this blocking is released, I can check the state of EC2 is 'stopped' on AWS console page. BUT,)
a[0].state
{'Name': 'stopping', 'Code': 64}

I expected 'stopped'.

This doesn't happens every time. Sometimes it works correctly.

Could you explain me how can I fix this?
Or if something I use those API with wrong way, let me know.

My python and boto3 version is

• Python: 3.6.8
• boto3: 1.12.39

Thank you!
