Hi,

I have an application which connects to sqs. I was able to create the sqs properly and below is the output

aws sqs list-queues --endpoint-url http://localhost:4566

 "QueueUrls": [
        "http://sqs.us-east-1.localhost.localstack.cloud:4566/000000000000/xyz-syncOrgList",
        "http://sqs.us-east-1.localhost.localstack.cloud:4566/000000000000/xyz-recreateFilesEvent",
        "http://sqs.us-east-1.localhost.localstack.cloud:4566/000000000000/xyz-updateOrgTable"
    ]

But the issue arises when I launch my app from using docker compose then it throws below error.

Caused by: com.amazonaws.SdkClientException: Unable to execute HTTP request: Connect to sqs.us-east-1.localhost.localstack.cloud:4566 [sqs.us-east-1.localhost.localstack.cloud/127.0.0.1] failed: Connection refused (Connection refused)

Could you please help me how I can fix this issue.

Hi @MummanaSubramanya,

Please have a look at the default docker-compose.yml for LocalStack to set it up and visit our docs for the Network troubleshooting | Docs (localstack.cloud).
