Connectionstring doesn't work for Azure - asp.net

I've been looking for this and haven't found a decent answer.
It's about my connectionstring in my web.config of my ASP.NET MVC application
This is my connectionstring:
<add name="DefaultConnection" connectionString="Server=tcp:****.database.windows.net,1433;Initial Catalog=***;Persist Security Info=False;User ID=****;Password=******;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" />
I also have a second, which works perfectly:
<add name="treinsqlEntities" connectionString="metadata=res://*/TreinDB.csdl|res://*/TreinDB.ssdl|res://*/TreinDB.msl;provider=System.Data.SqlClient;provider connection string="data source=*****.database.windows.net,1433;initial catalog=*****;user id=*****;password=******;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
It works perfectly on localhost, but it doesn't online, (The database and site is hosted on Azure) so the pasword and username are definitly correct.
I use this connectionstring to log in/register, sign up, ...
What's the problem?
Huge thank you in advance to all you lifesavers!
Edit: This is the exception:
enter image description here
These are my firewall settings: enter image description here

That is likely because you have not opened the firewall up to all azure connections. By default there are no firewall rules added to your new databases/server in Azure. You have probably added your local client IP but not checked the box that is for all Azure connections. https://learn.microsoft.com/en-us/azure/sql-database/sql-database-firewall-configure#overview The section 'Connecting from Azure' should point you to the right setting.
Please be aware that this allows all IP's originating from Azure a connection into you DB. It does not allow access since your authentication mechanism will stop that but connections will be allowed from any subscription in Azure with this option checked.

How to connect ASP.NET app to remote SQL Server

I need help connecting my Web App to a remote database (SQL Server).
I have tried many suggested solutions but I can't seem to come right.
This is how I connect to a local database, it works 100%:
<add name="DBCS" connectionString="Data Source=serverName;Initial Catalog=MVNE_Website;Integrated Security=True" providerName="System.Data.SqlClient" />
My ASP.NET Web App is hosted on one server, and the database is on a separate server.
The remote DB server is 100% configured to allow remote connections and firewall rules also adhere to the connection protocols. I think it is just my connection string that is incorrect but I don't know why??
Here it is(conn string for remote SQL server)
<add name="DBCS" connectionString="server=serverIP\serverName; database=MVNE_Website; Integrated Security=True" providerName="System.Data.SqlClient" />
I don't use a username or password when connecting to this remote SQL Server so I did not see a point in adding it in the conn string?
There can be a few reasons why this will not work. Here are 2 common ones:
Your web application will pass the username the application pool is running under, (which by default is some system user) to SQL Server. Change this to be a service account which has access to SQL Server.
If you are hopping across 2 or more servers to pass the credentials between IIS and SQL Server, you may need to implement Kerberos, which is a way to preserve the credentials. This is a complex network configuration thing.
Check point 1 first.
:/
In my web.config file custom errors mode was on RemoteOnly, so I turned it off and saw that my connection string was never the problem, the actual problem was that the app was trying to insert null into a primary key field that does not allow null, i never set the PK to auto increment
.. sorry and thanks

Where I made mistake guys ? Any help ?
Check with security group of your rds where CIDR /IP - Inbound Rule may be changed make it 0.0.0.0/0 this solved my issue hope it is useful

Proper format for SQL Server Connection String on 1and1.com

I have spent several hours trying to search this on the web in addition to calling and emailing support at 1and1.com web hosting with no success.
I have ASP.NET pages which connect to MS SQL Server database using the entity framework. On my local machine, all works fine (naturally). However, when I modify the connection string in my web.config to point to my SQL Server database on 1and1.com, I get the following error:
"Unable to load the specified metadata resource."
Here's my current connection string (as defined in my web.config file):
<add name="TimeDataLicenseEntities"
providerName="System.Data.EntityClient"
connectionString="metadata=res://*/
Model1.csdl|res://*/
Model1.ssdl|res://*/
Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=dbXXXX.db.1and1.com,1433;
Integrated Security=false;
initial catalog=database_name;
user id=dboXXXX;
password=valid_password;multipleactiveresultsets=True"" />
(Please note that where there are 'XXXX' the values are different in the actual config file as well as for 'database_name' and 'valid_password')
I'm using the Entity Framework in the code so I'd prefer solutions that correct the content of my web.config file.
Here is what ended up working for me:
<add name="TimeDataLicenseEntities"
providerName="System.Data.EntityClient"
connectionString="metadata=
res://<assemblyname>/Model1.csdl|
res://<assemblyname>/Model1.ssdl|
res://<assemblyname/Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=dbXXXX.db.1and1.com,1433;
Integrated Security=false;
initial catalog=database_name;
user id=dboXXXX;
password=valid_password;
multipleactiveresultsets=True"" />
By including the assemblyname for my code in the sections above (the brackets ('<' and '>') should not be included), I was able to finally get it to work.
Thanks all for your assistance.
Here is what actually works on 1and1 server from ASP.NET Code first design. So, simply replace your serverName, DatabaseName, UserID, and Password.
<add name="DefaultConnection"
connectionString="Data Source=dbXXX.db.1and1.com,1433;Initial Catalog=dbYYYYY;Integrated Security=False;user id=dboZZZZZ;password=YOURDBPASSWORD;MultipleActiveResultSets=True;Application Name=EntityFramework"
providerName="System.Data.SqlClient" />
Hope this can help anyone looking to use 1and1 asp.net server since their customer service is pretty useless.

how can i connect to database from IIS 5.1

When I want to connect to my site database via the local networkŘŚ This message will appear:
Cannot log in to my_server_name/AspNet
My connection string is:
<connectionStrings>
<add name="behbahan_cementConnectionString" connectionString="Data Source=MAYA-1307F9F334\SQLEXPRESS;Initial Catalog=behbahan_cement;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>`
I can't connect to the database?
I'd suggest you first try and establish whether you can connect to the database from outside the web application either via SQL Server Management Studio or by using a .UDL file. I've answered a question on testing a SQL server connection here.
Based on the results of these tests it may become apparent to you what the problem may be. In your case, you are using integrated security (which you would need to be on a domain to use over the network). If you are not on a domain, a username and password may need to be supplied.
Standard way to connect Database as;
<connectionStrings>
<add
name="NorthwindConnectionString"
connectionString="Data Source=serverName;Initial
Catalog=Northwind;Persist Security Info=True;User
ID=userName;Password=password"
providerName="System.Data.SqlClient"
/>
</connectionStrings>
What I can See here is you are messing ;
ID=userName;Password=password"
to connect the database in connectionString. Default username and password should be "root" unless you have changed it.
Try to connect with this detail.
Thanks,

SQL Server Express 2008 Connection Error (26)

So I have few ASP.NET apps all running off SQL Server Express 2008 and working fine and dandy. I just put up a new one to test something and am now getting the Error 26 - can't find instance. What's weird is that the app is talking to the DB partially because it brings up the user login page and if I enter wrong data it returns a message about that (which is good). When I enter the correct login info it takes it then thinks for a few seconds and then throws the Error 26.
Here is my connection string --
<connectionStrings>
<add name="db_BPEntities" connectionString="metadata=res://*/App_Code.Data.db_BP.csdl|res://*/App_Code.Data.db_BP.ssdl|res://*/App_Code.Data.db_BP.msl;provider=System.Data.SqlClient;provider connection string="data source=LOCALHOST\SQLEXPRESS;initial catalog=db_BC_Build;user id=USER;password=PASSWORD;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="Default" connectionString="server=LOCALHOST\SQLEXPRESS;database=db_BC_Build;USER ID=USER;password=PASSWORD;Min Pool Size=10;Max Pool Size=800;Network Library=dbmssocn" providerName="System.Data.SqlClient" />
</connectionStrings>
Note: I've changed user/password info. The DB is running locally off the same box with IIS (it's a test intranet site so I'm ok with that for now).
So summary:
Other apps running off same DB have zero connectivity issues. They all connect and work fine.
This app partially works but on login throws the Error 26 - Instance not found.
Would it be that there are 2 connection strings here vs 1 connection string on my other DBs?
Really stumped.
Thanks for any/all help :)
Edit: I think the issue is with the Entity Framework and SQL Server Express. It seems to connect initially to authenticate the user, but then the EF connectivity to display data, etc is where it breaks. That's where I'm at right now and stuck in trying to figure this out (I didn't develop this application).
Try to connect without "Network Library=dbmssocn" in your connectionstring. I have had the same (error 26) issue and it did work for me.
I change app config file to this
<connectionStrings>
<!-- TLPL_ICT_OPR\MSSQLSERVER1;Initial Catalog=FMS;User ID=fms -->
<add name="DBConnectionString" connectionString="user id=fms;data source=TLPL_ICT_OPR\MSSQLSER;persist security info=True;initial catalog=username;password=password" providerName="System.Data.SqlClient"/>
<!--<add name="DBConnectionString" connectionString="user id=fms;data source=TLPL_ICT_PHOLIB\SQLEXPRESS;persist security info=True;initial catalog=FMS;password=fms4321"
providerName="System.Data.SqlClient" />-->
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
after this it works fine....
To quote from SQL Network Interfaces, error: 26, these are the steps to overcome this issue:
Make sure your server name is correct, e.g., no typo on the name.
Make sure your instance name is correct and there is actually
such an instance on your target machine. [Update: Some application
converts \\ to \. If you are not sure about your application, please
try both Server\Instance and Server\\Instance in your connection
string]
Make sure the server machine is reachable, e.g, DNS can be
resolve correctly, you are able to ping the server (not always
true).
Make sure SQL Browser service is running on the server.
If firewall is enabled on the server, you need to put
sqlbrowser.exe and/or UDP port 1434 into exception.
