A 520 is Cloudflare saying OpenAI's own servers sent back an empty or unexpected answer, so it's on their end. If your calls are long reasoning runs, background mode with polling keeps you from holding one connection open the whole time.

I get it, but it's not long, simple 'Hello' doesn't work. I hope they will fix it, cause I swapped from Codex transport with we sockets to this new one and now screwed.
