So i am trying to make a face recognition system for my iot using cloud for the image processing right, and then i am gonna use render as for my cloud of choice the free one. and everytime i tried to post / send a pic to the cloud its always “502 Bad Gateway”, but then if i try to GET it works or if i try to POST without any attachment it outputed the correct sentence within the code if there no attachments. why is it like that ? does anyone have a clue ?
