AWS S3 CLI - Could not connect to the endpoint URL

Question

$ aws s3 ls

Could not connect to the endpoint URL: \"https://s3.us-east-1a.amazonaws.com/\"

What could be the problem?

Answer 1

If none of solutions given above works,also check your permissions and firewall settings. In my case adding proxy environment variables did the job.

For Linux or mac

$ export HTTP_PROXY=http://:

$ export HTTPS_PROXY=http://:

For Windows

set HTTP_PROXY=http://:

set HTTPS_PROXY=http://:
