We use the Zoom API to retrieve Zoom user account information daily at UTC 15:00, but since January 2026, “502 Bad Gateway” errors have started occurring frequently. Sometimes the process completes successfully, but in many cases, it results in an error. If an error occurs, running the process again usually completes successfully.  
We changed the execution time to UTC 21:00, but the frequency of occurrence did not change.  
After obtaining debug logs, we found that the error is being returned from Cloudflare.  
Is there any solution to this issue?
