I can't figure out what I'm doing wrong here. I've tried everything: my connection string, turned off firewall, allowed remote connections, but I still keep getting this error:

Any advice would be appreciated, I feel like I'm just overlooking something!
That simply states it could not establish a connection to the server and there could be dozen reason for that .
It could be the SQL-SERVER configured Windows Mode Authentication and you are trying sql-server authentication .
Or your sql-server is not configured for the remote connection
or you are using wrong credential .
or worst your connection string is not correct.
Any way , I highly recommend use Server panel in VS , and make test connection on that panel , It's much easier for you to figure it out what's wrong .

I recently uploaded a database driven application to a hosting service called Somee.com.
When querying data from the database via a gridview controll, it works perfectly. I am even able to update the data using the edit functionality in gridview.
However when I try to insert new data into the database, I get this error:

My asp.net application was working fine on my machine. For testing purpose, I moved the whole project on different machine.
Now everything is working except login. I am able to load data in my web site from database so I believe no issue with connection string.
I am using FormAuthentication with my own SQL Server database (have a separate table in my application database) and EF 4.0.
Here is the error message...

Someone help please?
I know this is an old thread. But, by any chance, are you trying to change the app.config file during runtime?
it happened to me, and #Evk gave me a great explanation of what was happening.
I have encountered a problem when trying to connect an ASP.net web application to SQL Server Enterprise edition after I added the following packages:
Microsoft.AspNet.Identity.OWIN
Microsoft.AspNet.Identity.Core
Microsoft.AspNet.Identity.EntityFramework
When I try to register a user I get this error exception.
I created a test method to test that the connection is working fine and it connected fine to my database server.

just wording when I install the packages it should be install tables for ASP.NET Identity
check your database connection - your application is not able to connect to database.
It will be in your web.config file in ConnectionSettings.
That is the reason for this 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 configured to allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)
Maybe the app.config has a good connection string for your unit tests vs the web config which has another connection string.

If that's your entire web.config file, then the membership provider will be using an auto-created database in your App_Data folder, which relies on the server having SQL Express installed.
Since the SqlMembershipProvider can't connect to the database, the server you've deployed to doesn't have a local instance of SQL Express installed. You'll need to configure the provider to talk to a real database, which you'll have to create in advance.
See this answer for more details.
