Losing progress on SQL course after closing VS Code and Docker

So I’m trying to do the SQL course by building a student database, and every time I close the docker and VS Code I can’t get back into the DB. I don’t have all the project files in my explorer and I get this error when trying to connect again:

“psql: error: could not connect to server: Connection refused
Is the server running locally and accepting
connections on Unix domain socket “/var/run/postgresql/.s.PGSQL.5432”?”

Is there something I’m doing wrong, and can I fix this or is it just how it is for now?

I am facing this error, too. Have you resolved it? @xRaizel

No I haven’t, and the answers I’ve gotten in another topic didn’t fix it. How about you?
