I have a .Net Core 6 console application that connect to a local SQL Server, this works fine on my dev computer. But when I try the same application on the server where the database is installed it doesnt work, I get an error telling me it cannot find the database. What could be wrong?
Update, I had to add the following to my connection string to get it to work.
;Trust Server Certificate=true

I'm using Umbraco CMS v7.4 with SQL Server 2014, the project was working fine until a few hours ago, when an error started showing up:
Umbraco cannot start. A connection string is configured but the Umbraco cannot connect to the database
The error occurs when I tried to open the website, see the image below:
I tried the following:
Checked to see if SQL Server is running
Checked the connection string credentials in web.config
Any help is appreciated.
After a few tries, even I loaded the backed up DB, I found that it caused by the DB login, the user in the connection string was having a password expiration enabled (the password had expired).
So, this is what I did:
Open the SQL server
Logged in as the user used in the connection string
Created a new password
Updated the web.config connection string "Password"
Hope this will help
So, in my case I tried to get started with the existing project. I got all the files, restored DB backup locally, made sure all permissions are set for IIS AppPool user etc. But I kept getting the error in question. It turns out that I cannot use server=localhost;database=... in connection string. After I replaced it with server=.\;database=..., it started to work right away.
Also note that if you're running it in Azure with an Azure SQL database you'll have to go to the Azure SQL Server settings and under "Firewalls and virtual networks" you'll need to tick "Yes" for "Allow Azure services and resources to access this server".
I was getting this error when running an Umbraco project locally, with the DB pointing to an instance on Azure. In that case, this problem happens if you haven't allowed the IP access within the Server Firewall of the DB in Azure.
You can fix this by finding out your IP and then adding it to the DB:
Click All Resources within your Azure portal, then click on the SQL Database your project points to.
Click Set Server Firewall on the right-side window.
Add in your IP as the start and end points, and call it something memorable.
Click Save and once you get the confirmation message that It has been applied, refresh your site locally.
I experienced the same problem and here is how I fixed it.
Right-click on your localhost in SSMS and select Properties
Got to the Security page and select "Select authentication" as "SQL Server and Windows Authentication mode"
Hit OK.
Go to Services and find your SQL Server service and restart it.
Check your local umbraco website now, you should be able to see it without any issues. If you still have problems, then you might need to check your local setup and permissions.
Further details are below and on this blog post.
I'm trying to install Umbraco on an ASP.NET environment. After I downloaded the umbraco nuget package I tried to run the installation wizard, by building and running the project. All is fine and good, if i take the default database configuration, but if I want to customize my configuration, it fails and says :
"Could not connect to database"
I'm trying to configure it to use my local SQLExpress database, but I just cannot get it working. I have both tried putting in the server information and connecting via. a connection string, via. the wizard. It produces the same error every time.
I have made a database called umbracoblog and created an admin user, with credentials. He has dbowner etc. for the database. Besides that, I have also given full permissions to IIS_IUSRS and Network Service accounts for the project and all subdirectories, and it still doesn't work.
These are some of the connection strings I have tried:
datalayer=SqlServer;Data Source=.\SQLExpress;Initial Catalog=umbracoblog;User Id=admin;Password=********;
datalayer=SqlServer;Data Source=127.0.0.1\SQLExpress;Initial Catalog=umbracoblog;User Id=admin;Password=*******;
I have also tried putting in the connectionstring into the web.config, manually, but that just makes the project load infinitely in the browser, when I run it.
It's starting to get frustrating, that I cannot even get past the configuration of Umbraco, because it look very cool. I have tried everything I was able to found online. Have anyone gone through this and know what I need to do ?
Start again - clear out and remove the umbracoDbDSN connection string entirely from your web.config and reset the umbracoConfigurationStatus AppSetting back to empty if it has been populated.
Use the Wizard to configure the database - if it's still having problems connecting then here's a few things to check:
Check the Log file here: ~/App_Settings/Logs/UmbracoTraceLog.txt - does that show up any errors?
Make sure you can connect to the database using other clients - if Umbraco can't connect to it, chances are something else won't be able to as well.
What happens if you use Integrated Authentication? If that works, then it's most likely an issue with the username and password you specified.
The password I had for the SQL Server user had a character that the installation UI didn't accept. I changed the password to remove special characters and it was able to connect to the server again. I could successfully log in through SSMS with the previous password.
I have a Delphi application that is connected to SQL Server 2012. On my local, I've been able to connect successfully. I've also tried it on another VM, and it work fine. I deployed it on a Server, and it won't connect to the database. I check the connection string; it looks fine. I am not sure what I am doing wrong here.
SQL Server 2012 is installed on a different server
I can reached the server
I check the provider and it's using SQLNCI11
I have SQL Server 2012 Natice Client Install
I check and make sure that the username/password have access to the database, and they can login
What am I missing here?
Despite the fact that you can change the vendor lib in the provider, that change will have no effect as the name of the DLL is hard-coded into the provider. It will try to use sqlncli10.dll, no matter what the property is.
Install sqlncli10.dll and it should work.
I have a working SQL Server 2008 R2 Express installed on a Windows 2008 server on a cloud machine. All type of connections (ado.net, nhibernate etc.) from several client applications works fine except the OLEDB one. SQL Native Client also works fine.
When I tried to connect from the server locally and as a data source write the instance name, everything was OK. But from outside, I had the problem or also if I write wan ip or dns I had the problem also from local.
-- works perfect from everywhere
Provider=SQLNCLI10;Data Source=mntek.no-ip.org;User ID=xxx;Password=xxx;
-- does not work from anywhere
Provider=SQLOLEDB.1;Data Source=mntek.no-ip.org;User ID=xxx;Password=xxx;
-- works only from local
Provider=SQLOLEDB.1;Data Source=flz001\sqlexpress;User ID=xxx;Password=xxx;
Error: [DBNETLIB][ConnectionOpen (Invalid Instance()).Invalid
connection.
-- works perfect with ado.net
Data Source=mntek.no-ip.org;User ID=xxx;Password=xxx
Some other client applications (not mine) was written with oledb connection so I need them to connect the db with oledb provider.
Any ideas?

It has been a while since this was asked, but I am currently working through an issue related to OLE DB and SQL Server that sounds possibly related.
I found that, even though the server was using the default port (1433), I still had to explicitly specify it in the UDL connection string like this:
Provider=SQLOLEDB.1;User ID=USER;Data Source=IP,1433
I've asked why that might be necessary here:
Why might SQL Server 2008 OLE DB UDL require port 1433 explicitly specified?
Maybe try that and see if it helps.
I'm working to try and get a migrated Umbraco/YAF installation working, but I'm having issues with connectivity.
I've already asked for help with the Connection Strings, so this bit is sorted.
However, I still get a 404 error when I try and navigate to mysite/forums, as it redirects to mysite/install
This site tells me that this could be because of a few issues:
It will connect you to install\default.aspx if
: its connect to a db but thinks there isn't a YAF version present in its data, or
: database version doesn't match and thinks it needs updating.
I know it's connecting to the DB, because the CMS connection string works, and it's connecting to the same database.
There are YAF_* tables in the database, so I know it's content is there.
By process of elimination, it might be a version issue, but I'm not sure how to compare the DB version to the ASP files version.
I'm running Umbraco 4.6.1
I never quite worked out what version I was running, but I did find out this issue was fixed by:
Assign yaf database user db-owner privileges.
And there you have it.
check that you have the following line in web.config
<add key="umbracoConfigurationStatus" value="4.6.1" />
