Answer 1

I was facing this issue today. Mine was Asp.Net Core API and it uses Postgresql as the database. We have configured this database as a Docker container. So the first step I did was to check whether I am able to access the database or not. To do that I searched for PgAdmin in the start as I have configured the same. Clicking on the resulted application will redirect you to the http://127.0.0.1:23722/browser/. There you can try access your database on the left menu. For me I was getting an error as in the below image.

Enter the password and try whether you are able to access it or not. For me it was not working. As it is a Docker container, I decided to restart my Docker desktop, to do that right click on the docker icon in the task bar and click restart.

Once after restarting the Docker, I was able to login and see the Database and also the error was gone when I restart the application in Visual Studio.

Hope it helps.
