Connecting to Azure SQL with tokio (on mac) gives a Tls connection closed via error.

[AdsSengupta]

this is my code

let mut config = Config::from_ado_string("server=xxx.database.windows.net,1433;UID=xxx;PWD=xxx;TrustServerCertificate=true")?;
let tcp = TcpStream::connect(config.get_addr()).await?;
tcp.set_nodelay(true)?;
let mut client = Client::connect(config, tcp.compat_write()).await.expect("Failed!");

and I get
thread 'main' panicked at 'Failed!: Tls("connection closed via error")', src/main.rs:80:22

It works without issues on Windows except that the username needs to be set as user@xxx.database.windows.net

What version? I remember @esheppa fixing this a while ago already.

@pimeys Has there been a solution to this? I am currently running into this issue for my own project.
We are using version 0.4.8

I ended up using ODBC since it doesn't work on the latest release.

I believe it's a mac TLS issue since it works on Linux

We might need a developer using a Mac to fix this issue... Sent from ProtonMail mobile

It seems to be a problem with native-tls and Catalina:

rust-native-tls/rust-native-tls#151

[pimeys]

It would be really nice if somebody could debug this a bit, forking Tiberius and then in their app then pointing to this fork and seeing certain things first:

• See if it fails with Tokio and async-std both
• If async-std works, maybe trying to patch async-native-tls in Cargo.toml with

async-native-tls = { version = "0.4", default-features = false, features = [ "runtime-tokio" ] }

If none of these work, the problem might be with the system certificates (Catalina has more strict rules how big the certificate needs to be compared to the older mac versions).

Here's a ticket that might provide some useful information:
