private static function CurlFactory::retryFailedRewind in Auth0 Single Sign On 8.2

This function ensures that a response was set on a transaction. If one was not set, then the request is retried if possible. This error typically means you are sending a payload, curl encountered a "Connection died, retrying a fresh connect" error, tried to rewind the stream, and then encountered a "necessary data rewind wasn't possible" error, causing the request to be sent through curl_multi_info_read() without an error status.
