Timeout when connecting to DB over VPN #360

I have some code that uses bb8-tiberius and tiberius, everything works when i am inside the network where the server lives, but when connecting over VPN tiberius times out trying to create the connection. Other db tools like sqlcmd and azure data studio work. I added logging and set to TRACE, but can't see any reason why it would fail. Any assistance appreciated:

here is the code:

impl DbMigrationClient {
pub async fn new() -> DbMigrationClient {
#[cfg(feature = "gcp-secrets")]
let secrets_manager: Arc<dyn SecretManager + Send + Sync> =
Arc::new(GcpSecretManager::new().await);

    #[cfg(feature = "env-secrets")]
    let secrets_manager: Arc<dyn SecretManager + Send + Sync> =
        Arc::new(EnvSecretsManager::new().await);

    let connection_string = format!(
        "uid={2};password={3};database={1};server=tcp:{0};TrustServerCertificate=true;encrypt=true",
        secrets_manager.get_secret("SQLSERVER_NAME").await.unwrap_or_default(),
        secrets_manager.get_secret("SQLSERVER_DB").await.unwrap_or_default(), 
        secrets_manager.get_secret("SQLSERVER_USER").await.unwrap_or_default(), 
        secrets_manager.get_secret("SQLSERVER_PASSWORD").await.unwrap_or_default());



    println!("Connection String = {}", connection_string);
    let mgr = bb8_tiberius::ConnectionManager::build(connection_string.as_str()).unwrap();
    let pool = bb8::Pool::builder().max_size(12).build(mgr).await.unwrap();

    DbMigrationClient {
        client: welds::connections::mssql::connect(connection_string.as_str())
            .await
            .unwrap(),
    }
}

Here are the logs on trace
