Hello @Rohit Chaturvedi ,
Thanks for reaching out.
Are you using a VPN client or a proxy to connect to the internet? Because this is most likely a network connectivity issue, I would recommend that you to verify that https://graph.microsoft.com/v1.0/ is whitelisted, as you may see graph endpoint called when I expose an API (aka identifieruri) from browser Devtool .
Try using incognito / InPrivate browser to check the behavior across different browser and lets know the outcome. Thanks.
Hope this helps.
