docker private registry change from v1 to v2 while pulling an image - docker

Question

There is a docker is registry v2.
An image is pushed to docker private registry. Able to see it using curl command:
$ curl -s -X GET http://<registry>:<port>/v2/<image>/tags/list
{"name":"<image>","tags":["latest"]}
However, not able to pull the image from other machines. It appears that it is trying to pull from v1 instead of v2
Pulling the above image on a windows 10 machine.
docker pull <registry>:<port>/<image>:latest
Getting the following error:
Pulling repository <registry>:<port>/<image>
Network timed out while trying to connect to
http://<registry>:<port>/v1/repositories/<image>/images.
You may want to check your internet connection or if you are behind a proxy.
Not using any proxy settings.
