I have a microservice application where I have APIGateway to accept all the incoming requests and redirect to the respective microservice after performing some validation checks. All is working fine until I am using http/https requests. But recently I have implemented a mobile application where I need a chatting option for this we implemented a flutter application and a microservice to handle the request. If I call the service directly, it works perfectly, but when I register my new microservice in APIGateway so that all requests come via APIGateway, it starts failing.

i have made 1 microservice user microservice. its application.yaml file looks something like this
