Magento2 – Getting error Could not find a matching version of package After submitting in packagist.org

I have Created New Module and uploaded in github.

Module Name : vrajeshpatel4u/helloworld

Url : https://github.com/vrajeshpatel4u/helloworld/

Packagist Url : https://packagist.org/packages/vrajeshpatel4u/helloworld

Below command I have tried still getting error : Could not find a matching version of package vrajeshpatel4u/helloworld. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (stable).

git add .
git commit -m 'initial commit'
git push origin master
git tag 1.0.0
git push origin --tags

Here is the composer.json

{
    "name": "vrajeshpatel4u/helloworld",
    "description": "Simple Hello World Module for Magento 2",
    "type": "magento2-module",
    "version": "1.0.0",
    "license": [
        "OSL-3.0",
        "AFL-3.0"
    ],
    "authors": [
        {
            "name": "Vrajesh Patel"
        }
    ],
    "minimum-stability": "dev",
    "require": {
        "php": "~7.1.3||~7.2.0||~7.3.0"
    },
    "autoload": {
        "files": [
            "registration.php"
        ],
        "psr-4": {
            "V4U\Helloworld\": ""
        }
    }
}

For installing Modules I have tried below commands :

composer require vrajeshpatel4u/helloworld

composer require vrajeshpatel4u/helloworld:dev-main

Any one help me to fix the issue?

Thank you.
