The provided connection string is invalid or the server is inaccessible

After downloading the code, set OrcardCore.Cms.Web as the startup option, press Ctrl+F5 to run it, and the browser will open the installation interface https://localhost:44300/ After entering all the text as required and clicking on 'Finish Installation', it will prompt that the provided connection string is invalid or the server is inaccessible

Is there any incorrect information filled in

I used to have to add TrustServerCertificate=True when installing on local:
Server=server; Database=db; User Id=sa; Password=password; TrustServerCertificate=True

[hehetiger]

I tried your suggestion, but it still didn't work.
I also tried 'Data Source=.;Initial Catalog=Orchard;Persist Security Info=True;User ID=sa;Password=123456;TrustServerCertificate=true' ,it didn't work either.
Do I need to execute certain commands to create a database first?

[duxonline]

Yeah, I remeber I created an empty database first.

[hehetiger]

What command to execute to create? Or just need to create an empty database whithout any tables?
