I am hosting a website on GoDaddy and getting database connectivity error while connecting to MySql database.
The error is coming as "Connection must be valid and open."
This error is coming while establishing the connection itself.
The language used is C# in MVC3.
Database server : MySql
Following is the connection string that I am using to connect to database.
<connectionStrings>
<add name="Application_Database" connectionString="Server=50.62.209.43;Protocol=TCP;Port=3306;Database=#####;Uid=#####;Pwd=######;" providerName="MySql.Data.MySqlClient" />
</connectionStrings>
Further, I would like to inform that the same connection string (provided above) is working on my local system and other servers also, but it is not working on GoDaddy hosting server.
Please help me out in this issue.

I'm getting the following error when trying to log into my system in asp.net (locally and IIS)
Login failed for user 'sa'.
The problem is that in no connection string we are using the SA login to connect to the database (SQL SERVER 2008).
Using the same connection string user and password, I can seamlessly connect to Management Studio ..
<add name="AppConnectionString" connectionString="Data Source=**IPADRESS**;Initial Catalog=**DATABASE**;Persist Security Info=True;User ID=**USER**;Password=**PSW**" providerName="System.Data.SqlClient"/>
An error also appears from time to time, altering with that of SA
No process is on the other end of the pipe
The site was in production for over 3 weeks and we had no problem so far ..
Can it be some IIS configuration, or will it be SQL?
I'm trying to connect to MySQL from my asp.net website on a hosted platform. My connection string looks fine, all the login details and server IP are correct but I am still getting an error on the page:
[Win32Exception (0x80004005): The network path was not found]
provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
web.config connection string:
<connectionStrings>
<add name="Conn" connectionString="Server=xxxx;Database=xxxx;Uid=xxxx;Pwd=xxxx;" providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
Can you guys give me any more info why this might be the case? Thanks!
Your server is not running or if running, your code cannot access this - firewall, etc. Or you didn't granted privileges for the IP of your app.
Looks like on this occasion there was a random Import that was making my site think it was using MSSQL rather than MySQL. Removed this and it's now working. Thanks for the help!
I copied an entire ASP site from a remote server to my local machine. I can access the homepage, but once I try to login to the rest of the site, 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 configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified)"
I set things up to allow for remote connections (enabling TCP/IP and Named Pipes), but is the problem because I'm trying to access a remote database? The connection string in Web.Config is:
<connectionStrings>
<add name="ISBEPI_DEV" connectionString="Data Source=ERI-DB-06\DEVELOPMENT;
Database=ISBEPI_DEV; Initial Catalog=ISBEPI_DEV;Persist Security Info=True;
User ID=Pi_usr; Password =J6$h3Qoz#9Yw;" providerName="System.Data.SqlClient"/>
</connectionStrings>
Any help would be very much appreciated! Please let me know if I can provide more info. Thanks!
Looks like you specified incorrect connection string or you are not allowed to connect to that SQL server. Have you tried to connect to that database from SQL Management Studio or Server Explorer in Visual Studio?
I am working through an ASP.NET MVC4 tutorial from ASP.net. This is the second tutorial in which I am getting database connection errors. Here is the error:
An error occurred while getting provider information from the database. This can be caused by Entity >Framework using an incorrect connection string. Check the inner exceptions for details and ensure that >the connection string is correct.
Here are my connection strings. The first one was generated by the template, the 2nd was copied verbatim from the tutorial. I am running SQL Server 2008, not express. That may be my problem. The database is created automatically from the application as well. I do not have a login / password that I am aware of for this local db.
<add name="DefaultConnection"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-MvcMovie-20130830102032;Integrated Security=SSPI"
providerName="System.Data.SqlClient" />
<add name="MovieDBContext"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Movies.mdf;Integrated Security=True"
providerName="System.Data.SqlClient"/>
I've looked on connectionstrings.com & asp.net to find a resolution and I am not clear on the fix. The error has to be in the connection string, but I am unsure which one, if not both, it is.
Thanks
I just changed the data source to Data Source=. and here is the error now:
There is already an object named 'PK_dbo.Movies' in the database.
Could not create constraint. See previous errors.
I tried to delete the database in sql server and was unable to when right clicking on it and pressing delete. Any ideas?
Setup
MVC 3 EF 4.1 Code First - Windows 7 Pro 64 Dev machine, Separate Win 7 Pro for host.
I started with a SQLCE4.0 database, and everything worked fine (database initializer created tables, populated, etc...).
Once I got everything working like I wanted, I scripted out my SqlCe DB, created a real SQL 2008 DB, opened the proper ports and enabled TCP connections.
Problem
IF I Change my connection string to point to my intranet server\instance name, with a user I created for this app specifically, it works perfectly running from my dev machine.
IF I publish the app to the server (the web server and sql server are the same), and I try to login to the website (aka access the db), then I get:
CREATE DATABASE permission denied in database 'master'.
I commented out the DBInitializer setup so nothing should be created upon a db hit. The tables are there already.
If I do Database.SetInitializer(null); then I get a different login error:
I don't remember exactly but it was something to the affect of LOGIN FAILED FOR IIS APPPOOL\ApplicationPoolIdentity
So I changed the Identity to NETWORK SERVICE and even tried LOCAL SERVICE, both giving the same login failed error.
I tried following this post who says add a SQL user named 'IIS APPPOOL\MyApplicationName'. SQL Wont let me do that as it has invalid characters ... go figure.
Why does it work perfectly over the network accessing the DB from my dev machine, but when I publish to THE SAME machine that hosts the sql and the site, I get permission denied or login failed errors? I've scoured the net and tried different things.
EDIT: Here are my connection strings:
<add name="AntripContext" connectionString="Data Source=|DataDirectory|AntripWeb.sdf" providerName="System.Data.SqlServerCe.4.0" />
<!--<add name="AntripSQL" connectionString="Data Source=.\sqlexpress;Initial Catalog=Antrip;User Id=myuser;Password=mypassword;" providerName="System.Data.SqlClient" />-->
<add name="AntripWebEntities" connectionString="metadata=res://*/DAL.AntripEntities.csdl|res://*/DAL.AntripEntities.ssdl|res://*/DAL.AntripEntities.msl;provider=System.Data.SqlServerCe.4.0;provider connection string="Data Source=|DataDirectory|\AntripWeb.sdf"" providerName="System.Data.EntityClient" />
<!--<add name="AntripWebEntities" connectionString="metadata=res://*/DAL.AntripEntities.csdl|res://*/DAL.AntripEntities.ssdl|res://*/DAL.AntripEntities.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.\sqlexpress;Initial Catalog=Antrip;User Id=myuser;Password=mypassword;"" providerName="System.Data.EntityClient" />-->
Note: The commented out connection strings are the ones that use the sql 2008 database (that break my published app).
It sounds to me as if your connection string has Integrated Security=true so that you are connecting to SQL as the user you specify, rather than the SQL user you think you are using?
But beware, its still trying to create a database: you need to swap the IDatabaseInitializer - I guess it will look for a DB named the same as the entitys to be careful!
