I have a very weird issue with SSAS Tabular connecting to a SQL Server source database. I've spent almost the entire day on this, and searched online in various ways to find a helpful answer, but none of the suggestions solved this mysterious problem for me.
It used to work fine, but I tried various connection settings (Windows vs SQL authentication, and different impersonation modes), but now I no longer can get it to work (even if I revert back to the previous bim file in source control).
When I process a table from the WORKSPACE database (through SSMS), it works. But when I process a table from the DEPLOYED database (still through SSMS), it does NOT work.
The connection I am using is:
-SQL Server Native Client 11.0
-Windows Authentication
-Impersonation mode of a Windows account (which has the appropriate permissions)
The source database is in a SQL Server database located on a different server (but in the same network).
I have searched everywhere online, but didn't find anything that could help me.
I have tried changing the connection driver (OLE DB Provider for SQL Server), and I have restarted the SSAS Tabular service.
The full error message I get when trying to process a table on the deployed database is:
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: Login timeout expired; HYT00; A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.; 08001; Named Pipes Provider: Could not open a connection to SQL Server [5]. ; 08001.
A connection could not be made to the data source with the Name of 'DataWarehouse'.
'.
In fact, after I tried a second time to restart the SSAS Tabular service, the error message I get after attempting to process a table is slightly different:
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.; 08001; SSL Provider: The requested security package does not exist
; 08001; Client unable to establish connection; 08001; Encryption not supported on the client.; 08001.
A connection could not be made to the data source with the Name of 'DataWarehouse'.
'.
According to your description, it seems to be related to connection problem. You need to check whether corresponding SQL server service and SSAS Service is running(check server which contains "DataWarehouse" is running and can be connected). You could go to "SQL Server Configuration Manager " to restart them.
In addition, you also need to make sure your current windows credential can access this database(if you use window credential). And check whether this server enable remote connect.

Trying to connect to SQL Server from Excel by using >>Data tab, >>From other sources >> from SQL server. It came back with the attached message
I made sure named pipes and TCP/IP are enabled in the SQL server configuration manager. It works on my laptop. But my friend is trying to install in her laptop and it is not working. Appreciate any ideas you can share with us. We are doing Developer Edition, custom install of the database server. Double checked the instance name and made sure remote connection is allowed.
This is the error message I get
Unable to connect:

I have read this thread, however unfortunately couldn't find the solution to my problem. I have an ASP.Net Core project (that's called Rent) and it works without any problem on my local machine. However, once I publish the project to the IIS (still in development mode) I get the below error
fail: Rent.Program[0]An error occured during migration

The connection string is called DefaultConnection and is the environment variable. Can anyone help me please? Can provide any additional information if required.
The first thing you should check is that your SQL Server instance is up and running and that your database is still available. This error means quite literally that it can't establish a connection to SQL Server from the Secret Server application.
And you can also check follow things in your environment:
Is something blocking the connection between your Secret Server server and SQL Server?
The standard SQL port is 1433. Check with your server administrator - is the Windows Firewall in use, blocking this port on your SQL server? Check with your network administrator - is there a firewall at some point in between that has closed off this port? Keep in mind that if you use a custom port for SQL, it need to be specified the Secret Server database connection using a SQLSERVER,port type of format.
On the server hosting your SQL Server database, is the SQL Server
service running?
Open services.msc or SQL Configuration Manager to view the status of your SQL Server service.
I am trying to create an OLE DB connection in SSIS that I want to use for this package I am building which basically is supposed to do an ETL having it's source from Excel and the output in a SQL table. However, I am getting the error as below when trying to connect to the server and check in. I am using windows authentication and trying to connect locally using the '.' I also couldn't find the sql server configuration manager in my computer. I reinstalled my management studio 2018 version, but the didn't fix it either. Any insights would help on resolving this issue.
Thanks

I've installed tigertoolbox from Microsoft and I'm using SQL Server Performance Dashboard Report daily.
It's very useful and I suggest you to install it if you are not using it yet.
BTW, when I connect to localhost everything works smoothly but when I'm trying to connect to another SQL Server instance on the network I receive the error

The answer is very easy: I can easily connect to localhost thanks to my credentials but I need to enter user/password for a remote SQL Server instance.
How can I ask to SSRS to prompt user and password for remote SQL Server instance?
The problem Cannot create a connection to data source ‘DataSource1’. (rsErrorOpeningConnection) is even mentioned in the comments on the official Microsoft page but it's not mentioned how to fix this issue.
Check if you are running the SSRS on the default port of Server. If not, inform the port in the connection.

That is NOT the answer.
The error tells you that your server was not found, so it cannot be authentication error, the server is not reached so it just cannot authenticate you.
You should check your connection string if it's right. if it's correct, it can be firewall or your server is not configured to accept remote connections.
So for whe first thing post here your connection string, it looks like this:

For the past month I have been using Microsoft SQL Server Management Studio tool to connect to my database which created on the Azure portal. Recently I received updates from Microsoft related to Microsoft Visual Studio. After I installed these, I can't connect to my SQL database (previously it was working fine). Update History Screenshot I attached the screenshot of recent updates (which I installed) and the error message for your view.Error Message
Please help to solve this issue.
note: I am an SQL beginner, so I don't know many technical things related to tools, so please keep your answers to my level, Thanks!

The network path was not found
This error means that you tried to create a connection to an endpoint and you were expecting a acknowledgment from sql server, however, that acknowledgement did not occur. This means that you are either blocked by your own network, a network in route, or the endpoint network (which all three could be your own if, running locally). I would start by pinging that server ip address and seeing what you come up with.
that problem solved automatically, when I tried to keep connecting. really I don't know what was the problem..thanks for ur reply guys.
