What is the reason for the error code "Bad Gateway 502"?

I am using the ChatCompletion object and on some of the requests, I get the error code of “Bad Gateway 502”. I am able to handle it using try, catch but I am unable to find a reason as to what results in this error code? Is it random or is there something related to the prompt (sensitive prompt for eg) that is going on? I did not find it in the error codes in the documentation.

Exact message is this:

root:OpenAI API error: Bad gateway. {"error":{"code":502,"message":"Bad gateway.","param":null,"type":"cf_bad_gateway"}} 502 {'error': {'code': 502, 'message': 'Bad gateway.', 'param': None, 'type': 'cf_bad_gateway'}} <CIMultiDictProxy('Date': 'Sun, 05 Nov 2023 01:07:51 GMT', 'Content-Type': 'application/json', 'Content-Length': '84', 'Connection': 'keep-alive', 'X-Frame-Options': 'SAMEORIGIN', 'Referrer-Policy': 'same-origin', 'Cache-Control': 'private, max-age=0, no-store, no-cache, must-revalidate, post-check=0, pre-check=0', 'Expires': 'Thu, 01 Jan 1970 00:00:01 GMT', 'Server': 'cloudflare', 'CF-RAY': '8211251fcaaa07e4-IAD', 'alt-svc': 'h3=":443"; ma=86400')>

I’m new to using this API so someone else might know exactly what’s going on, but can you clarify how frequently you receive the 502 response and if this is new behavior or has been happening consistently for a long period of time?

Also, if you can, providing more context by answering some of these questions would help rule out some things and provide insight on others:

  • Do your API requests that encounter the 502 code only occur on specific devices, networks, or times of the day?
  • Do your API requests get routed through a proxy server, VPN, or originate from a network with custom firewall configurations?
  • Can you confirm if sending a subsequently identical request gives you a different response?
  • Do you have other API calls that are sent without issue at the same time you receive the 502 error code? If not, have you already tried immediately sending an API call you know would be safe to make when you receive the 502 error response?

It is nothing within your control. It is an error from Cloudflare that the destination IP of the OpenAI API behind their firewall could not be reached.

Hi @openai hope you doing well.

i have this problem in AWS lambda i have handle try and except bolck but when ever i got delay in response i check in logs and it turn out 502 error but still dont know why is this frequently happening i got 2 correct and 3rd on got 502 error but it got me delay like the fail request almost took 5 to 7 mint on lambda for response.
it is wasting my execution time on Lambda .

here is the errro:

  "errorMessage": "Bad gateway. {\"error\":{\"code\":502,\"message\":\"Bad gateway.\",\"param\":null,\"type\":\"cf_bad_gateway\"}} 502 {'error': {'code': 502, 'message': 'Bad gateway.', 'param': None, 'type': 'cf_bad_gateway'}} {'Date': 'Thu, 16 Nov 2023 08:06:07 GMT', 'Content-Type': 'application/json', 'Content-Length': '84', 'Connection': 'keep-alive', 'X-Frame-Options': 'SAMEORIGIN', 'Referrer-Policy': 'same-origin', 'Cache-Control': 'private, max-age=0, no-store, no-cache, must-revalidate, post-check=0, pre-check=0', 'Expires': 'Thu, 01 Jan 1970 00:00:01 GMT', 'Server': 'cloudflare', 'CF-RAY': '826e2cf0cba77f86-IAD', 'alt-svc': 'h3=\":443\"; ma=86400'}",
  "errorType": "APIError",

i dont know its AWS Services Network problem or Openai.
