Error When Trying to Update RDS Database in ASP.NET Visual Studio Environment

So I've been struggling with this issue for a while. When I run Update-Database in Package Manager Console, I get the following output.

System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

I have verified that I am able to connect to my RDS Database in SQL Server Management Studio, and I can also open it within Server Explorer in Visual Studio itself. I am able to run Enable-Migrations with no issue as well. Below are my connection strings and where I initialize the DBContext. The connection string is the one provided when I connect to my DB in Visual Studio.

web.config

<connectionStrings>
    <add name="dbname" connectionString="Data Source=dbname.xxxxxxxxxxxx.us-east-2.rds.amazonaws.com;Initial Catalog=dbname;User ID=username;Password=password;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False" providerName="System.Data.SqlClient" />
</connectionStrings>
<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"/>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
</entityFramework>

Context.cs

public class ApplicationContext : DbContext
{
    public DbSet<Team> Teams {get; set;}
}

I had done a similar project before, but I did not face much issue with the connection string automatically adjusting to my database. I do believe I have adjusted the security groups for my RDS instance to enable public accessibility and given all security groups access.

Any help would be appreciated, and if more information is needed I will gladly provide it. I am also able to build and run the project perfectly fine.
