Error 504 for request documentGeneration.status (GET)

Hi , I am receiving Gateway Timeout issue for  documentGeneration.status api with error code 504001 returned from Adobe.This is happening when request id generated from  documentGeneration(POST) api has happened few days back.This issue is not happening when request id generated from  documentGeneration(POST) api is immediately checked in documentGeneration.status GET call.So older request ids are not helping get access to the downloaded document.Please let me know if I need to provide more details.
