Open metadata is not getting connected from SDK

[RupaDosapati]

I have deployed the open metadata using docker. It is running on docker container.
https://docs.open-metadata.org/latest/quick-start/local-docker-deployment

I was trying to run standalone java SDK to connect to open metadata but getting below error.
https://github.com/open-metadata/openmetadata-demo/tree/main/java-sdk-examples
feign.FeignException$InternalServerError: [500 Internal Server Error] during [GET] to [http://host.docker.internal:8585/api/v1/version] [CatalogApi#getCatalogVersion()]: [{"responseMessage":"An exception with message [HTTP 404 Not Found] was thrown while processing request.","errorType":"UNHANDLED_SERVER_EXCEPTION"}]
at feign.FeignException.serverErrorStatus(FeignException.java:259)
Even trying to access the api's from postman getting this error
{
"responseMessage": "An exception with message [HTTP 404 Not Found] was thrown while processing request.",
"errorType": "UNHANDLED_SERVER_EXCEPTION"
}
Can some one help what is the problem here.
Thanks
