[🐛 Bug]: Unable start session, status code 500, net::ERR_CONNECTION_REFUSED

[ctron]

What happened?

Starting a new session using:

let caps =  DesiredCapabilities::chrome();
let driver = WebDriver::new("http://localhost:4444", caps).await?;

It fails with:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: an unknown error occurred in the remote end whilst processing the command: unknown error: net::ERR_CONNECTION_REFUSED
  (Session info: chrome=117.0.5938.92)', integration-tests/src/ui.rs:111:43

Sniffing the traffic on port 4444 shows a 500 status code on the last message:

I am not sure how this release TBH.

What I did notice however was that it's doesn't seem to be related to podman, but also fails on GitHub actions with plain docker.

Recently there was a feat #2008 to resolve issues related to status 500. Can you try a newer image tag? (at least 4.15.0-20231122)

[VietND96]

We closed the ticket with the fixes in build number provided and no more inputs for a long time. Kindly reopen if it occurs again. Thanks!
