cannot use docker with proxy in win10

Question

I want to use Docker in win10 with a proxy for that I use GUI to set a proxy in the settings, I add this:

   http://127.0.0.1:9090

but it won't work it always returns the same error

docker login
WARNING: Error loading config file: C:\Users\mk\.docker\config.json: invalid character '"' after object key:value pair
Authenticating with existing credentials...
Login did not succeed, error: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.

Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

this is my config.json

{
  "stackOrchestrator": "swarm",
  "auths": {
    "https://index.docker.io/v1/": {}
  },
  "credsStore": "wincred"

}

this is how I configure the docker

I'm using win10 Pro and Psiphon3 for proxy
