Port for Docker pull

I am trying to pull a Jenkins image.

I am not behind a proxy - but have restricted internet - I need to open the correct port for docker for it to pull images

Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/jenkins/images. You may want to check your internet connection or if you are behind a proxy

Can anybody tell the exact port which I should open?

Should be mostly normal old 80/443 for HTTP/HTTPS
