Cannot connect to database during umbraco install

I have a clean project, which i am trying to get started. I have also created a clean database.

Both are running locally on my pc.

I can connect to my database with linqpad, with no issues. But when i try to "customize" and set a microsoft SQL server, it says

Could not connect to database

And in console, i get a 500 internal server error, on :

:62164/install/api/PostValidateDatabaseConnection

What can i do ?

Edit when trying to use a custom connection string, i get this :

If, even with a custom connection string, you still get a 500 error I think that you have a botched installation and you should try to reinstall Umbraco from scratch
