Azure: Login failed for user

What I have done:

• I added Resource group in Azure.
• Added Web Service with previous resource group.
• Added SQL Server Database with previous resource group.
• Retrieved generated connection string from this database and provided here username and password.
• Added this connection string to App Settings in Web Service.
• Published app via Visual Studio.

Problem: I get this error when I tries to test this hosted app in azure, but on my local version of app and exactly this connection string everything works just fine..

Server Error in '/' Application.
