lambda connection timed out while accessing SQS

Question

We are using Lamda and passing SQS que as environment variable and The lambda is in a VPC in Public subnet with Internetgateway attached, the role attached to the lambda has SQS Full access, but we are getting the error as below ""errorMessage": "Unable to execute HTTP request: Connect to sqs.ap-south-1.amazonaws.com:443 [sqs.ap-south-1.amazonaws.com/10.0.0.69, sqs.ap-south-1.amazonaws.com/10.0.0.39, sqs.ap-south-1.amazonaws.com/10.0.0.53] failed: connect timed out",
  "errorType": "com.amazonaws.SdkClientException",

Answer

To access SQS from a Lambda in a VPC, you must either create a VPC endpoint, create a NAT gateway, or manually set a public IP address in the Lambda's ENI.  
If you are on a public subnet, it would be easy to set up a VPC endpoint.

Answer

The answer from Riku_Kobayashi is correct but I'd like to comment on something else in the question:

The endpoint name is `sqs.ap-south-1.amazonaws.com` but the error you're getting shows that it is resolving to private IP addresses (10.0.0.69, 10.0.0.39, 10.0.0.53) and that's curious. Do you have anything in your VPC which is acting as a DNS server that is trying to send your traffic to some other endpoint?
