Issue while pulling docker image x509: certificate signed by unknown authority

Hi,
We have a Azue VM with docker running on it. Now when I tried to pull any image from docker hub I am getting following error. The issue is same with all the docker images like busybox or ubuntu etc,

docker pull alpine

Using default tag: latest

latest: Pulling from library/alpine
da9db072f522: Pulling fs layer
error pulling image configuration: Get https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/blobs/sha256/63/63b790fccc9078ab8bb913d94a5d869e19fca9b77712b315da3fa45bb8f14636/data?verify=1733392202-Xg3Oq7SQx8%2BNZ6NYUWe1fyY5Vgc%3D: x509: certificate signed by unknown authority

But When I tried to pull an image from Microsoft repo like below its not throwing any errors.

docker pull mcr.microsoft.com/windows-cssc/python:3.9-nanoserver-ltsc2019

Can anyone help me out on this issue?

Looks like something plays man in the middle and breaks the security context: the usual suspect is tls inspection
