Hi,
Currently, I'm facing an issue where I have configured a URL into our mailer and when we are receiving the testing the URL is accessible from my mailbox but when I'm trying to access it through the mirror page. It's showing the below error.

We tried using some common URLs like https://www.google.com and it's working fine on the mirror page. It would be great if you can help us understand what's causing this issue.
We are currently on build v7 9032.
Regards,
Himanshi
