Not able to use Docker, even though the demon status is active

I am attaching my question from StackOverflow, due to very little response I figured this forum is a better place to resolve my query.

I tried using docker on Ubuntu LTS 22.4 and failed to pull the hello-world image, then I downgraded my OS to LTS 20.04 and the problem persists.

Docker Version: Docker version 20.10.17, build 100c701

docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": proxyconnect tcp: dial tcp: lookup http: Temporary failure in name resolution.

sudo docker login

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)

My demon is active:

I see it’s only 3 hours old (maybe closer to 2 hours when you posted here and it was flagged as spam), and some people are trying to help in the comments there. Some patience, please? Kudos for adding the link to the original question; please also add the debugging info from the comments here. And keep the two places in sync…

Wanted to add that the problem persists on CentOS and on my friends computer :slight_smile:
