Why can't the VM inside Docker swarm find the image?

Question

Computer networks

I'm reading the Docker documentation and settled on the swarm section ( https://docs.docker.com/get-started/part4/#accessi... I created two VMs, clustered them, connected to swarm-manager and tried deploy my application (5 instances of my container are launched.) I register docker stack ps applicationand see a lot of errors "No such image: quadtree/...." Logically, each VM should have loaded the image from docker.hub, but for some reason this is not I tried on the
swarm-manager VM to run a simple command to start the application:
docker run -p 80:80 quadtree/web-application"
And I got this as a result:

Unable to find image 'quadtree/web-application' locally
docker: 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).
See 'docker run --help'.

Apparently the VM can't connect to Docker Hub. How can this be fixed?
