Why is my web server not validating my certificate?
This issue occurs because the website certificate has multiple trusted certification paths on the web server. For example, assume that the client computer that you’re using trusts Root certification authority (CA) certificate (2). And the web server trusts Root CA certificate (1) and Root CA certificate (2).
How are SSL certificates used to validate identity?
SSL certificates that are made use of while validating a server’s identity to the client. Digital files that are utilized for the validation of a client’s identity to the server. Plain text data in transmission gets converted into cipher text. No conversion of data from plain text to cipher text takes place.
Upon hearing these two terms, one can’t help but think that ‘Client’ certificate must be related to the client and ‘Server’ certificate to the server. That’s not entirely correct but it’s a good place to start. Server certificates (SSL certificates) are used to authenticate the identity of a server.

When do you get a null reference exception?
A NullReferenceException happens when you try to access a reference variable that isn’t referencing any object. If a reference variable isn’t referencing an object, then it’ll be treated as null. The run-time will tell you that you are trying to access an object, when the variable is null by issuing a NullReferenceException.
What does it mean when a reference type is null?
Reference types default to null to indicate that they are not referencing any object. Hence, if you try and access the object that is being referenced and there isn’t one, you will get a NullReferenceException. When you get a NullReferenceException in your code it means that you have forgotten to set a variable before using it.
