Cannot bind Domain to Web App

Hello,

I deployed an Azure App Service Web App for my accounting firm website.

When attempting to bind my custom domain and enable HTTPS, the binding fails and outbound POST requests from my contact form are not working.

This appears to be a new subscription trust restriction. The site is a legitimate small business informational website with a simple contact form and is not used for bulk email or marketing.

Please review my subscription and remove any domain binding or outbound communication restrictions so I can attach my business domain and operate the website normally.

Domain: XXXXXXXXXXXXXXX.com

Web App Name: XXXXXXXXXGroup

Thank you.

    Hello @Admin

    Thank you for confirming that the issue is resolved. As mentioned, when checked in backend certificate is bind to the domain. As suggested by community member @TP may be the issue could be with registering the domain.

    Hi,

    I checked and the domain you posted does not appear to registered yet. Did you register it with a domain registrar? You would need to do that first before you can add it to your web app as a custom domain.

    Perhaps you misspelled the domain in your question?

    Thanks.
