I encounter the same issue

We encountered the same 401 error but found a different root cause: Python on macOS had zero CA certificates loaded (ssl.create_default_context().cert_store_stats() returned all zeros), causing HTTPS authentication requests to fail. curl worked fine because it uses system certificates, but Python's SSL module had an empty certificate bundle. Setting SSL_CERT_FILE=/path/to/certifi/cacert.pem in our environment fixed it completely - authentication succeeded and traces uploaded without 401 errors.

This appears to be a separate issue from the async auth race condition described in PR #1270. Our case was a pure SSL/TLS certificate verification failure that happened before any authentication could complete. Common on macOS when Python is installed via homebrew/pyenv without the certificate installer script.

Ran into the same issue above in February 2026. Setting the cert path at the beginning of main.py fixed it for me.
