@Beera.Rajesh, These (HTTP 502 and 504) and other errors seem related to service outage, and the recommended action for an application is to try again.

You didn't mention when client received these errors, but there seem to be some service alerts related to DSS recently. If this keeps happening, please open a service ticket - and get product team to investigate it. This does not seem to be an API issue.

502 Bad Gateway
            BadGatewayException
            
                The server, while acting as a gateway or proxy, received
 an invalid response from the upstream server it accessed in attempting 
to fulfill the request.
            
            Retry=yes
