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!
Update: Error Message
TITLE: Connect to Server
Cannot connect to abcxyz.database.windows.net.
ADDITIONAL INFORMATION:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
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.

Dear stackoverflow community,
I have a problem using Direct Query connect in Power BI. I have an SQL Express server running on a remote server with a Linux operating system. I connect to this server using a VPN. I can connect to this SQL server with my local MS SQL Express installation no problem. I can also import the data to my local Power BI desktop installation using Get Data>SQL Server>Import.
However when I try to use Direct Query, it fails after executing for a while and setting up the Direct Query connections. I receive the following Error Message:
"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: Named
Pipes Provider, error: 40 - Could not open a connection to SQL
Server);The network path was not found. The exception was raised by
the IDbConnection interface."
It's also interesting that it appears like something is loading in the fields pane
I feel it could be a problem with allowing remote connections in the Linux remote MS SQL Express Server, but have found no way of allowing this in Linux. On my Windows installation it's no problem.
I'm really excited to solve this issue and start building my dashboard. But I need a live connection for that...
Thank you for your time reading this and your replies in advance.
This was solved by using the 64 bit version Power BI from the microsoft store and not adding the portnumber when making the sql connection. I recommend admins not to delete this as finding this solution wasn't too straightforward.
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.

I have configured a SQL Server 2016 alias following this post and it was working, but suddenly it stopped working.
Error message:
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: TCP Provider, error: 0 - The wait operation timed out.) (.Net SqlClient Data Provider)
I created the alias using the SQL Server Configuration Manager and created it in the 32 and 64bit:
When I go to the Protocols for SQL Server Express, all of them are enabled, thus TCP/IP is enabled. Also, the SQL Server Browser service is running.
Looking at the system log there is no relevant message about it, so I'm a bit lost about what could be causing it to stop working. My OS is Windows 10 Pro.
Would you have any clues to help me solve it? Thanks for any help
Check that the SQLEXPRESS instance's port number hasn't changed, which is likely after a reboot or service restart.
Regarding the use of instance aliases, this is pretty much useless if you're also using dynamic ports for this very reason. To me it's more cumbersome to maintain this configuration than it is to maintain a connection string in your program IMHO.
I configured the SQLAzure database. I configured the firewall for my IP and when am trying to connect to that database from my local using SQL Server Management studio, getting below error
TITLE: Connect to Server Cannot connect to XXXXX.database.windows.net.

The network path was not found
How to resolve this issue?
Please also check network protocol when you connect to Azure database via SSMS. It seems you are using named pipes and TCP/IP is excepted.
Hi Bravo are you able to browse the instance via Visual Studio if you have it installed?
Can you also confirm that you are not behind a corp firewall that blocks 1433 outbound?
Really minor thing but the title of the error has a trailing "." which if that is the machine name you are trying to connect to won't work - it may just be appended by the error message.
You can try a few things:
Ensure SQLAzure database name is correct (the error that you posted translates to name doesn't even exist)
Try adding port number at end of the connection
XXXXX.database.windows.net,1433
If the issue still persists, try pinging the SQLAzure from your local machine.
Okay so a lot of people have posted a similar question, however I don't seem to be able to find a solution to my problem in any of them. So this is my situation.
Yesterday I was working with my SQL Server Express through SQL Server Management Studio. I close my projects as I've done multiple times before and then this morning when I tried to connect again with the tool is gives me this error:
TITLE: Connect to Server
Cannot connect to .\SQLExpress.
ADDITIONAL INFORMATION:
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) (Microsoft SQL Server, Error: -1)
I think my main question here is if there is a solution to this problem, or if I have to install SQL Server Express all over again?
PS: Here are some system stats. I'm working on a Windows 10 machine, and the SQL Server Management Studio version is 2014.
Open SQL Server Configuration Manager
Click on SQL Server Network Configuration and click on Protocols for Name
Right click on TCP/IP (make sure it is Enabled), click on Properties
Select IP Addresses Tab and go to the last entry: IP All
Enter TCP Port 1433.
Now restart "SQL Server .Name." using services.msc (winKey + r)
I had the same problem but a different solution. My protocols was configured correctly but I was still getting the problem. In SQL Server Configuration Manager make sure that the SQL Server Browser is configured to start automatically and is running. As soon as the service was active my problem disappeared.
this issue also confusing me a few days after the IT guy do some security settings to the SQL Server. i have an EntityFramework for the Web application and a desktop application. after i did some setting on the SQL Server, the Web application comeback to work, but the desktop still with issue. but i used the some connection string for the both application, it make no sense one is work but the other doesn't. then i searched a lot until i found some one said need add a port number 1433 after the $ServerName$DatabaseInstanceName,1433 at here http://www.windows-tech.info/15/9f6dedc097727100.php . after i added it. the exception became: System.Data.SqlClient.SqlException: Login failed for user 'domain\name-PC$'. then i found this link System.Data.SqlClient.SqlException: Login failed for user : System.Data.SqlClient.SqlException: Login failed for user it said need add Trusted_Connection=False;. the whole connection string should be like: data source=XXXXX\SQLSERVER,1433;initial catalog=XXXDB;user id=UserID;password=PWD;Trusted_Connection=False;MultipleActiveResultSets=True;
hope this answer will help the ones out off Generic exception: "Error: 26-Error Locating Server/Instance Specified)
