How to implement guide with `sqlx` and async database connections leading to connection timeout errors in 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.
