When I have tried to connect to localhost and it was displayed the message about
"mssql:Error 2: 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)".
How can I fix it?
I have tried to follow the solution technique given by "Why am I getting "Cannot Connect to Server - A network-related or instance-specific error"?" but i can't find the location of vscode mssql extension configuration tool and SQL Server Configuration Manager?
You may be changed your computer name. if you changed your computer name then back to set initial name of computer. Then restart your Sql Server(MSSQLSERVER)service.

I have docker that running on kubernetes, the site is able to browse from the browser. When performing request API, that requires a connection to the database.
The database is hosted on SQL Azure NOT on another docker.
I got 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.
How to troubleshoot and fixed the issue?
I have found the issue, The issue is dockerFile connectionString is still using the one in appsettings.json.
I have passed the environment like this
kubectl run identityapi --image xxxxxxxx.azurecr.io/panda/identity.api --port=80 --env="ASPNETCORE_ENVIRONMENT=Development" --env="ConnectionStrings__DefaultConnection=Server=xxxxxxxx.database.windows.net,1433;Initial Catalog=panda.identity;Persist Security Info=False;User ID=xxxxxxxx;Password=xxxxxxxx;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"
The environment for ConnectionStrings__DefaultConnection must use double underscore instead of dot (.)
I am trying to connect to MSSQL via Visual Studio Code with installed mssql extension. I did pull and run SQL Server 2017 container image with Docker and I am trying to make a connection, although I do get an error:
mssql: Failed to connect: System.Data.SqlClient.SqlException
(0x80131904): 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: 25 - Connection string is not valid)
---> System.Net.Sockets.SocketException (0x80004005): Undefined error: 0 at System.Data.SqlClient.SN
The container image is running - I did log on to MSSQL through terminal, but I can't with Visual Studio Code. Do I have to provide an instance as well? Where I can find it - cannot find it on docker inspect statement.
Did you guys have similar problem and maybe found a solution?
Okay I managed to solve the problem. I do connect to sql server container on 1401 port (localhost,1401 on VSC), but apparently when you start a container you need to change the password for sa. Rookie mistake :) Thanks for trying to help
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!

First you need to check whether SQL SERVER service is running in your system or not .For checking follows below steps in Windows.
Step 1 : Type "window" button + R ,This will open Run prompt.
Step 2: Type "services.msc" in Run prompt and hit the enter.
Step 3: Find SQL SERVER service from there.
Step 4.Start this service.
Following these steps, I have resolved this problem in my machine.
Thanks
Check your SQL Server Service is Running or not
if the server is in remote location check port 1433 is not blocked by the firewall.
if this is not the default instance, Check SQL Server Browser is running or not
Check the network connection on client PC, and verify the connection to the server using PING or TELNET
Check whether TCP/IP and Named Pipes are enabled or not.

This is how am trying to connect to my Azure:
And I have noticed one more error in SQL Server Services, But all the services are running.
The remote procedure call failed. [0x800706be]
PS: I have also added my IP address in the "Manage IP Addresses" in windows azure.
Any ideas!
This is a very generalized question. There can have many reasons due to which you are getting this network related error.
Have you ever got it work before? Are you sure server name is correct? Can you cross check?
Or else you can check the internet connectivity and working of VPN(if you use it)
