Hi @Sebastian Ene ,
The error message that your offered is a common SQL server connection failed error. It is not related to SSMS. Please follow below steps to troubleshot this issue. From your screenshot, it seems you do not have a complete SQL server installation, you can get SQL 2019 setup file from here. You can follow the steps from this blog to install SQL server 2019.
- Make sure SQL Server Service is running
- If a named instance, make sure SQL Server browser service is running. Make sure the instance name is spelled correct and there is actually such an instance on your target machine.
- Make sure SQL Server is configured to allow remote connections
- Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
- Test server connectivity with PING from the client machine
- Test port connectivity using TELNET to the server and port (from step 4) from the client machine. For example
TELNET <server-name> 1433 - Check firewall settings if step 5 or 6 connectivity test fails
If you have some confuse about the steps, please refer to Resolving could not open a connection to SQL Server errors or Troubleshoot connecting to the SQL Server Database Engine to get more information.
