WCF Cancel off Security Error

Question

An error occurs during software login: "the caller was not authenticated by the service"

However, I have previously applied the security mechanisms of X509 and have now cancelled them all. However, I still receive an error message and cannot log in. I have no issues on my Windows 7 computer and Windows 10 computer, but there will be error prompts on the Windows Server server.

            name="basicEndPoint"
