[Solved] ASP.Net Core Error: The certificate chain was issued by an authority that is not trusted

I am trying to add a model (table) to a SQL Server database, but I am getting an error.

Here is what I tried - in program.cs:

builder.Services.AddDbContext<DataContext>(options =>
options.UseSqlServer(builder.Configuration.GetConnectionString("Default")));

In appsettings.json I have:

"ConnectionStrings": {
    "Default": "Server=RWAHDAN;Database=HSPA2024;Integrated Security=False;User Id=sa; Password=mypassword;"
},

And this is my City model class:

public class City
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Lastly I have my datacontext:

public class DataContext : DbContext
{
    public DataContext(DbContextOptions<DataContext> options): base(options) {}

    public DbSet<City> Cities { get; set; }
}

Migration is ok but updating database is not.
