@Nigam Kumar It is possible that the issue is related to the configuration of your Azure App Service. However, it is also possible that the issue is related to the link itself.
One way to troubleshoot this issue is to check the browser console for any error messages that may be related to the link. You can also try opening the link in a new tab or window to see if it works outside of your web app.
If the link works fine outside of your web app, then it is possible that there is a configuration issue with your Azure App Service. You can check the configuration settings for your web app to ensure that everything is set up correctly.
