I can connect without any problem to my Sql Server (network service) at home or anywhere else except at work. Sometimes it gets a spirit of the moment connection and then just disconnects again.
It keeps giving me this error:
==========================================================================
Cannot connect to winsqls02.cpt.wa.co.za.
==========================================================================
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) (.Net SqlClient Data Provider)
--------------------------------------------------------------------------
I have tried restarting my laptop, pinging the server, changing to another router at work, but nothing seems to work.
Is there maybe a simple reason for this issue, because I can't seem to find any answers on the internet.

I have a Blazor app that connects to an API. Both of them are on the same server (IIS).
Everything works fine, but after one or two days, when users try to log in, API returns this 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
---> System.ComponentModel.Win32Exception (53): The network path was not found.
I tried to reset all the SQL server services (SQL Browser, SQLSERVERAGENT,... ), but it didn't work.
I also tried to restart my website and web API in IIS, but it didn't work.
The only thing that worked is restarting the server!
What's the problem? Why do we get this error after a few hours?
I recently install SQL server 2014 in my PC and I selected SQL authentication rather than Windows authentication after completion of installation when I tried to log in my server it shows this error even my server name and password was correct even though it shows this what to do now!!

The network path was not found
As the error states "network-related or instance-specific error" its related not being able to find the instance.
This maybe due wrong instance name, Check the spellings of the server that you are connecting to.
You may have installed a named instance like sqlexpress in that case the server name should be {YourServer}\Sqlexpress.
You can get your instance name by going to services, if its MSSQLSERVER you can connect with the machine name else you should provide the correct instance name.
Please refer the screenshot below.
If you are connecting to another machine check the network configuration of the instance by going to sql server configuration manager. If the status is disabled you can connect from outside.
If that also fails better check the firewall settings
I have that problem i cannot connect to SQL Server.
I get this error:
Cannot connect to (localdb)\MSSQLLocalDB. 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

error: 50 - Local Database Runtime error occurred. Error occurred
during LocalDB instance startup: unable to create the SQL Server
process. ) (Microsoft SQL Server, Error: -1983577844)
I have looked all over the internet, but all of them are solutions that don't work for me, they show something like you just need to connect to your server the right way, and then make a user login.
But how can I do that if I can't get into my server or database.
I can't get any further than this picture
I even tried through Services that some fix it through, or SQL Server Configuration Manager but I don't have any SQL Server Services.
As you can see on this picture
Btw it's saying there is no elements to show.
I have no idea to what I can do now.
I try to search my problem and found lots of threads, but all of them server related. All suggestion/tips regrading Database server related.
I have a database server (SQL Server 2014) hosted on VPS. Server is running fine without any issue, and working fine from all computer over internet. But from one PC it is not connecting. I disabled antivirus, added program on exception list on firewall,but still I am unable to connect the server, while that server are access from other PC. This PC connecting on internet through cable internet connection and operating system is Windows 7 Ultimate (I called service provider, and confirmed that they are not blocking/filtering any IP).
Thanks in advance.

I'm getting error whenever I connect to the instance(DESKTOP-0LFC1LP) on Sql Server. I'm using Sql server 2012.
I don't know what's the reason but whenever I install Sql server , It works perfectly for a day or two and after that it starts giving me this error.
I can solve this by re-installing Sql and it will work fine but again only for a day. I want a permanent solution to this. And please also tell why it works after I reinstall it?
Your help would be appreciated!
