![]() The following example uses ping to confirm that the DNS resolves to the S3 endpoint: ping s3. The following example uses nslookup: nslookup s3. To confirm that your DNS can resolve to the Amazon S3 endpoints, use a DNS query tool such as nslookup or ping. Verify that your DNS can resolve to the S3 endpoints Note: Make sure to replace the Regional endpoint and the port (443 or 80) with the values associated with your use case. Verify that your network can connect to the S3 endpointsĬonfirm that your network's firewall allows traffic to the Amazon S3 endpoints on the port that you're using for Amazon S3 traffic.įor example, the following telnet command tests the connection to the ap-southeast-2 Regional S3 endpoint on port 443: Note: If you're using Amazon S3 Transfer Acceleration, see Getting started with Amazon S3 Transfer Acceleration for the endpoint name. You can get the "Could not connect to the endpoint URL" error if there's a typo or error in the specified Region or endpoint.įor example, the following command results in the error because there's an extra "e" in the endpoint name: aws s3 cp filename s3://DOC-EXAMPLE-BUCKET/ -endpoint-url īefore you run the cp or sync command, be sure to confirm that the associated Region and S3 endpoint are written correctly. Then, the AWS CLI can redirect the request to the bucket's Regional S3 endpoint. Or, API requests are sent to a Region-specific S3 endpoint when the Region is specified in the command. When you run a command using the AWS CLI, API requests are sent to the default AWS Region's S3 endpoint. Resolution Confirm that you're using the correct AWS Region and Amazon S3 endpoint If you're seeing this error on an Amazon Elastic Compute Cloud (Amazon EC2) instance, then check the Amazon Virtual Private Cloud (Amazon VPC) configuration.Verify that your DNS can resolve to those Amazon S3 endpoints.Verify that your network can connect to those Amazon S3 endpoints.Confirm that you're using the correct AWS Region and Amazon S3 endpoint.To troubleshoot this error, check the following: Note: If you receive errors when running AWS CLI commands, make sure that you’re using the most recent AWS CLI version. Otherwise, you get the "Could not connect to the endpoint URL" error message. To do this, follow the steps in My DB instance is in a private subnet, and I can't connect to it from my local computer.To run the cp or sync commands using the AWS Command Line Interface (AWS CLI), your machine must connect to the correct Amazon S3 endpoints. If the DB instance still isn't accessible after following these steps, check to see if the DB instance is Publicly Accessible. The DB instances are accessible from the internet if they have an associated public address. Important: If you change a subnet to public, then other DB instances in the subnet also become accessible from the internet. Note: Be sure that the Inbound security group rule for your instance restricts traffic to the addresses of your external or on-premises network. Then, select the internet gateway ID in the Target list. For IPv4 and IPv6 traffic, in the Destination box, enter the routes for your external or on-premises network. Choose Actions, and then choose Edit routes.ġ0. From the Description pane, choose the Route Table.ĩ. Choose the subnet that is associated to the DB instance that you found in step 5.Ĩ. Open the Amazon VPC console, and then choose Subnets from the navigation pane.ħ. The VPC subnet is based on the subnet CIDR range and private IP address.Ħ. ![]() After you have the private IP address of your RDS DB instance, you can relate the private IP address to a particular subnet in the VPC. ![]() My DB instance is in a private subnet, and I can't connect to it from my local computerĥ.
