/WebSocket connection to 'ws://localhost:9097/graphql' failed: Error during WebSocket handshake: Unexpected response code: 405

/Issue while hosting the graphql server on nginx

/Nginx.config websocket server setting

            listen       9097;
    server_name  localhost;
    location /subscription{         
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass http://localhost:3007;
    }

My graphql server is running locally on localhost:3007/graphql. But with above configuration socket is not getting created.

Getting below error:

WebSocket connection to 'ws://localhost:9097/graphql' failed: Error during WebSocket handshake: Unexpected response code: 405.

I have this configuration for nginx And this one in nestjs And the postman returns 400 when I'm trying to connect

For browser the same

So, I've found the solution, the problem was in postman, I don't know why, but websockets there is working inappropriate, btw, some problem was with nginx, I had two of them, on inside the docker container and the second main on the server, and I need to add the same thing (proxy_set_header etc.) to both of nginxs.
