I am experiencing an error when connecting MY DB which is in VM Role (I have SQL VM Role) from Azure Website. Both VM Role and Azure Website are in West zone. I am facing the following issue:

SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)]

I am able to connect to my DB using SSMS. Port 1433 is open on my VM role. What is wrong with my connection?
