When publishing MVC app on Azure, the connection string is picked automatically but I fail to understand how the deployed app connects to the database using this connection.
There's server error: SqlException (0x80131904): A network-related or
instance-specific error occurred while establishing a connection to
SQL Server. The server was not found or was not accessible.
How do I resolve this on Azure.

Trying to connect to an external datahub from a SSMS on a server. From desktop computer works.
Port 1433 allowed on server. Has anyone seen this or have a solution? Thank you.
Error:
Test connection failed because of an error in initializing provider. Client unable to establish connection due to prelogin failure
TCP Provider: The specified network name is no longer available.
Client unable to establish connection
Client unable to establish connection because an error was encountered during handshakes before login. Common causes include client attempting to connect to an unsupported version of SQL Server, server too busy to accept new connections or a resource limitation (memory or maximum allowed connections) on the server.
I have an instance of Azure Hybrid Connections running on a server where SQL Server is installed.
I hosted an WebApp on azure, set up the hybrid connection and I'm consistently getting the same SSPI Handshake error
SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The operating system error code indicates the cause of failure. The logon attempt failed [CLIENT: 1x.xx.xx.xxx]
As described here I added the clients ip in the local security policy.
I also tried adding the DisableLoopbackCheck=1 in HKLM\System\CurrentControlSet\Control\LSA, but it didn't help either.
Do I have to fix it on a database level perhaps?
As per https://github.com/Huachao/azure-content/blob/master/articles/app-service-web/web-sites-hybrid-connection-connect-on-premises-sql-server.md
[AZURE.NOTE] To ensure that your application uses the database that you created in SQL Server Express, and not the one in Visual Studio's default LocalDB, it is important that you complete this step before running your project.
Edit the connectionStrings section to point to the SQL Server database on your local machine, following the syntax in the following example:
I added user credentials to my connection string in appsettings.json and it now works.
I am trying to publish a VS2017 web app to a godaddy domain with authentication on a remote SQL server. The app works fine when run from the Visual Studio environment. I can log in, register, etc and see the data on my SQL Server. When deployed I get ::
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.)]
Fixed - I discovered that the web.config file on the domain server did not get updated with the proper connection string.
I have an Azure VM with port 1433 endpoint created. The internal IP is 110.119.38.72.
In my Azure Standard Website Web.Config connstring if have:
Server=110.119.38.72;Database=MyDB;uid=username;pwd=password;
I am getting the error:
[Win32Exception (0x80004005): Access is denied]
[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server.
See screenshot for more details:
If I change my connection string to the Public IP of my Azure Sql Server I am able to connection.
How can I used the Internal IP of my Sql Server VM in my Azure Website?
By default you can't. However, Azure websites now support running on a Virtual Network, so (in theory) you should be able to create a vnet and place both your SQL Server vm and the Azure Website on that vnet. That should enable you to connect to the db using the internal (vnet) ip address of the vm. I haven't tried this tho, so no guarantees.
Using Visual Studio 2010 10.0.20319.1 RTMRel and SQL Server Express 10.50.1600.1 I'm trying to add a new SQL Server Database .mdf, however, I receive the following error:
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is

I have enabled TCP/IP and Named Pipelines, added Firewall Exceptions for Sql Server, I am successfully connecting from VS in the Server Explorer window.
I would appreciate if someone can pint me to a solution to my problem.
Thank you.
I think that SQL Server must be running locally to be able to create those databases.
I was getting the same error
Started my local .\SQLEXPRESS instance
no more error, and a cute .mdf file was created
According to your error
(provider: SQL Network Interfaces,
error: 25 – Connection string is not
valid)
check here what your connection string should look like
