People also ask

How do I find my Amazon S3 endpoint URL?

Get an S3 Object's URL #Navigate to the AWS S3 console and click on your bucket's name. Use the search input to find the object if necessary. Click on the checkbox next to the object's name. Click on the Copy URL button.

Why can't I connect to an S3 bucket using a interface VPC endpoint?

To troubleshoot this error, check the following: Verify the policy associated with the interface VPC endpoint and the S3 bucket. Verify that your network can connect to the S3 endpoints. Verify that your DNS can resolve to the S3 endpoints IP addresses.

How do you check S3 endpoint is working?

To check that your VPC Endpoint for S3 is working correctly, find the URL of your target bucket in the AWS console and use the hostname there as the target of a traceroute command on one of your virtual machines in your SDDC.


You probably have something wrong in your default profile for the default region.

Check your file at ~/.aws/config, you have something like

[default]
region=us-east-1a
...

Fix the region to region=us-east-1 and then the command will work correctly


first you use 'aws configure' then input the access key, and secret key, and the region. the region you input would be important for this problem. try to input something like 's3.us-east-1', not 's3.us-east-1a'. it will solve the issue.


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://<YOUR PROXY IP>:<PORT>

$ export HTTPS_PROXY=http://<YOUR PROXY IP>:<PORT>

For Windows

set HTTP_PROXY=http://<YOUR PROXY IP>:<PORT>

set HTTPS_PROXY=http://<YOUR PROXY IP>:<PORT> aws cli Windows

enter image description here


Some AWS services are just available in specific regions that do not match your actual region. If this is the case you can override the standard setting by adding the region to your actual cli command.

This might be a handy solution for people that do not want to change their default region in the config file. IF your general config file is not set: Please check the suggestions above.

In this example the region is forced to eu-west-1 (e.g. Ireland):

aws s3 ls --region=eu-west-1

Tested and used with aws workmail to delete users:

aws workmail delete-user --region=eu-west-1 --organization-id [org-id] --user-id [user-id]

I derived the idea from this thread and it works perfect for me - so I wanted to share it. Hope it helps!


You should specify the region in your CLI script, rather than rely on default region specified using aws configure (as the current most popular answer asserts). Another answer alluded to that, but the syntax is wrong if you're using CLI via AWS Tools for Powershell.

This example forces region to us-west-2 (Northern California), PowerShell syntax:

aws s3 ls --region us-west-2

Probably, there is something wrong with the default region while configuring aws. In your case, the URL says "https://s3.us-east-1a.amazonaws.com/"

In your command prompt,

aws configure, enter your keys, Now fix your region from us-east-1a to us-east-1.

Kindly check the syntax according to the CLI you are using. This will be helpful.
