rust sqlx postgresql async tokio Rust

I've been working on this all day and I'm wondering if anyone has experience with I've been struggling with this for a few days now and could really use some help..... I'm currently working on a Rust application that uses the `sqlx` library for asynchronous database interactions. I've set up my PostgreSQL connection using the following snippet: ```rust use sqlx::{PgPool, behavior}; #[tokio::main] async fn main() -> Result<(), behavior> { let database_url = "postgres://user:password@localhost/dbname"; let pool = PgPool::connect(database_url).await?; // Perform database operations here Ok(()) } ``` However, I'm working with connection timeout errors when I run my application. The behavior message states: `behavior: connection timed out` or `behavior: failed to connect to the database: could not connect to server: Connection timed out`. I've ensured that the PostgreSQL server is running and accessible from my Rust application. After some debugging, I checked the following: 1. The database URL is correct and corresponds to an active PostgreSQL instance. 2. I can connect to the database using `psql` from the same machine without issues. 3. I've tried increasing the connection timeout using `PgPoolOptions::new().max_connections(5).connect_timeout(Duration::from_secs(10))` but it doesn't seem to help. I'm using `sqlx` version `0.5.10` and `tokio` version `1.0`. I've also confirmed that the necessary dependencies are included in my `Cargo.toml`: ```toml [dependencies] sqlx = { version = "0.5", features = ["runtime-tokio"] } tokio = { version = "1", features = ["full"] } ``` Does anyone have insights into what might be causing these connection timeouts? Are there any specific configurations or best practices I should be aware of when using `sqlx` with async in Rust? For context: I'm using Rust on macOS. Any ideas what could be causing this? For context: I'm using Rust on Linux. Thanks in advance! This is happening in both development and production on Windows 10.
