HTTP Error 404.7 - Not Found The request filtering module

Here is the background, I created project using VS and signed up with Azure Free Trial offer. With Azure I created new SQL Server and Database, and used their Connectionstring so that all my project files and tables are added to Azure SQL DB. After completing the Project I Exported the DB in .bak format, and then I signed up for Shared hosting with Hostgator.

Imported the .bak DB file in Hostgator SQL DB which I created. Hostgator provided me with ConnectionString which I inserted in web.config file of mine. Since then I am unable to connect to the DB and I am seeing following Error

HTTP Error 404.7 - Not Found The request filtering module is configured to deny the file extension.

Most likely causes: Request filtering is configured for the Web server and the file extension for this request is explicitly denied.

Things you can try: Verify the configuration/system.webServer/security/requestFiltering/fileExtensions settings in applicationhost.config and web.config.

Detailed Error Information: Module RequestFilteringModule Notification BeginRequest Handler StaticFile Error Code 0x00000000 Requested URL https://abc.in:443/Global.asax Physical Path D:\INETPUB\VHOSTS\abc.in\httpdocs\Global.asax Logon Method Not yet determined Logon User Not yet determined

More Information: This is a security feature. Do not change this feature unless the scope of the change is fully understood. If the file extension for the request should be allowed, remove the denied file extension from configuration/system.webServer/security/requestFiltering/fileExtensions.

Can some please look into this and help resolving this? Thank you in advance
