I run the mediasoup rust echo example on Ubuntu with cargo run --example echo, and it did start without error, but websocket connection just times out without any log or response.
I removed path from dependencies.mediasoup-sys in Cargo.toml that resulted this. After adding path back and build mediasoup-sys locally, the example works.
I was running it on Ubuntu. And I changed example dependency mediasoup-sys source from local path to crate.io 's (by deleting path key). The WebSocket server didn’t work with this dependency change. After revert this change back, it works well. : D
