Failed call to AWS CLI service in order to get ELB Data

i am running Ubuntu Machine and i installed awscli using pip.

after this i configure the service with a user with full access to read monitor data. My goal is to get a list of all my ELB at this Aws Account and go over all their instances.

this is the CLI command that i am trying to run :

 aws elb describe-load-balancers  --load-balancer-name "cpv" --region us-east-1b

i am trying a lot of diffrent combinations with the name , with - "" without "" i also configure the Region.

this is the reply i always get :

HTTPSConnectionPool(host='elasticloadbalancing.us-east-1b.amazonaws.com', port=443): Max retries exceeded with url: / (Caused by <class 'socket.gaierror'>: [Errno -2] Name or service not known)

it seems the AWSCLI is trying to call to a default host and not to my ELB. i also tried the following for the name :

  1. use the ELB - DNS_name and with http:// , and https://
  2. Use DNS record that call to the ELB CNAME
  3. Use with "" and without ""
  4. Use the name with <> , [] around it

It seems that my awscli is set on using this default host

elasticloadbalancing.us-east-1b.amazonaws.com

Is there any way to configure this ?

The results of all those tries where all the same .. Fail

does anyone know how to make this work?

After Running this format :

aws elb describe-load-balancers   --load-balancer-names "my-VIP" --endpoint-url http://my-VIP.us-east-1.elb.amazonaws.com --debug

I got this debug out put :

It looks like your region is set to us-east-1b. If you update this to us-east-1 it should work. You can do this via the --region us-east-1, setting the AWS_DEFAULT_REGION=us-east-1 env var, or adding "region = us-east-1" in ~/.aws/config.

This should work:

aws elb describe-load-balancers --load-balancer-names "your-elb-name"

where "your-elb-name" equals what you inputted into aws when you created it. It can also be found in the first part of the public end point aws supplies
