We are working on fully resolving this issue in the meantime you can try one of the workarounds:
On MacOS
_(by @alpha-adam)_
Run this in Terminal:
open /Applications/Python\ 3.11/Install\ Certificates.commandThis installs the required root certificates that Python uses for SSL.
After that, codex login should work without SSL errors.
*nix
_(by @thelonglincoln)_
export SSL_CERT_FILE=$(python3 -m certifi)
export REQUESTS_CA_BUNDLE=$(python3 -m certifi)before running codex login

I just published version 0.20.0 on npm (https://www.npmjs.com/package/@openai/codex) which includes https://github.com/openai/codex/pull/2042
If you have been running into issues related to the Python stuff, please update to 0.22.0 as we migrated the Python code to Rust in the new release: https://github.com/openai/codex/releases/tag/rust-v0.22.0
As an added bonus, 0.22.0 now supports Markdown and streaming!
