Do the Arduino firmware OTA using the surge. Does not return http status code 202

[jpily]

Hello everyone, I used Arduino Firmware OTA as a server file using Surge and it always worked.
OTA has not been carried out since then due to a power outage in the surge server
When http code returned 202, we coded OTA to proceed, but now we returned 304 so that OTA operation cannot be performed.
Is there a way to always return 202?
