This error was returned when I tried to connect with server. Error description is:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

If you are trying to connect to your Sql Server running on MacOS via Docker, then make sure that Sql Docker container is running and then you will be able to connect to your Sql Server using Azure Data Studio as shown in attached image Sql Container inside Docker

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

  1. Check your SQL Server Service is Running or not
  2. if the server is in remote location check port 1433 is not blocked by the firewall.
  3. if this is not the default instance, Check SQL Server Browser is running or not
  4. Check the network connection on client PC, and verify the connection to the server using PING or TELNET
  5. Check whether TCP/IP and Named Pipes are enabled or not.

for more details Why am I getting "Cannot Connect to Server - A network-related or instance-specific error"?
