Research direction

Start with the WorkflowServiceStubs.newLocalServiceStubs() call in the worker and compare its endpoint with the Docker deployment configuration. Run the worker and Temporal server together while checking connectivity to port 7233; done means the worker connects successfully and processes workflows in Docker.

Description

bug

When i try to connect temporal server from the worker class which is in my spring boot application i am getting below error message and worker is not able to connect with temporal server
i am using the below line to get the service stub

WorkflowServiceStubs service = WorkflowServiceStubs.newLocalServiceStubs();

io.grpc.StatusRuntimeException: UNAVAILABLE: io exception
Caused by: io.grpc.netty.shaded.io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: /xxx.x.x.x:7233

Both of my worker(spring boot application) and temporal server are deployed in my local Docker Desktop.
But if i launch both of them in locally (i.e not in Docker), i am able to connect each other and process the workflows.

Any clue on why only when i deployed this on docker and not in locally
