Hi @immaculate,
When k6 gets a 0 status error code it usually means some system issue (like we couldn’t dial the server in time).
The original error is logged on the cli and also there is error_code and error (smaller version of the original error) tags in the emitted metrics. So if you look at those you can actually diagnose this issue better. There is also a page with the error codes and what they mean.
edit: I update the link as I was linking to the CI build
