Maybe add some logic to wait until the server is ready

Hi @emdneto, I’d like to work on this issue
From the CI logs, it looks like the failure happens because the test tries to connect to 127.0.0.1:5000 before the server is fully ready, causing intermittent connection errors.
I’m planning to add a small readiness check (with retries) before running the tracecontext integration tests to ensure the server is up before tests execute.
Please let me know if that approach sounds good!
