How to configure Postgres on Heroku for my .net core web API

I have successfully deployed a .net core web API on Heroku, but the app fails to launch. When I attempt to run the app, I get the error below: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

Here is the connection string my .net core code

"ConnectionStrings": {
"DromiContext": "User=user;Password=password;Host=host;Port=5432;Database=database;Integrated Security=true;Pooling=true;"

}

Solution

The app was not configured to run migration automatically. After it was updated

using (var serviceScope = services.BuildServiceProvider().GetService<IServiceScopeFactory>().CreateScope())
            {
                var context = serviceScope.ServiceProvider.GetRequiredService<DromiContext>();
                context.Database.Migrate();
            }

The error disappeared
