I need help. I am learning webpages on my own personal azure trail account for 30 days.
Microsoft defender seems to block my test webpage to test how embedding works, but I cannot tell why.

This currently only seems to be an issue on Bing as chrome and Mozilla report no errors:
Error code

I have tried reaching out to Window Defender feedback, but I have heard back yet. So I submitted another request and before that I went through the following steps:

  1. Upgraded all the javascript packages to the latest versions and check each package in case there were any security vulnerabilities
  2. Added a Content Security Policy
  3. Made sure the default SSL key is a valid external SSL
  4. Checked the website across 14 different website checkers to make sure there were no security issues. In fact the whole purpose of the test pages was to test alternatives to 3rd Party cookies.

I have done everything I can, but it still shows blocked in Bing.

Can anyone help?
