520 errors through the responses API
OpenAI Developer Community
June 7, 2026
So - some interesting findings:
1: I kick-off a request using the openai SDK.
2: The request runs and after a minute fails with a 520.
3: If I go into the openai logs (https://platform.openai.com/logs), I can see the response. It has a response id and an assistant message with the response text I expect. It seems to raise an exception around 230 - 260 seconds.
