Final answer:
The issue that Chris should report is that self-signed certificates will cause warnings or error messages.
Step-by-step explanation:
The issue that Chris should report to his management is that self-signed certificates will cause warnings or error messages.
When a website uses a self-signed certificate, it means that the certificate was not issued by a trusted third-party certificate authority. This can result in warnings or error messages being displayed to visitors when they try to access the website.
For example, when a user tries to visit a website with a self-signed certificate, their web browser may display a warning message stating that the website's certificate is not trusted. This can create a negative user experience and potentially discourage visitors from using the website.
