Requests post not working with long processing time. about requests

At the end the solution I found, if anyone needs it, was not on the client side but in the server side. Something underneath is closing the connection after 275 seconds, so the solution was to create function in a threding.Thread, while the process is alive. It sends text messages every 30 seconds. In that way, both sides know that the connection is alive. I tested with a 5 minutes process. I used StreamingResponse to make it happen.

que = queue.Queue()
def director():
    # Esta funcion se utiliza para poder enviar mensajes periodicamente cada 30 segundos
    # es necesaria para mantener la conexión activa con el cliente en archivos que requeren 
    # más de 270 segundos para procesar
    resultado = ""
    t = Thread(target=lambda q, arg : q.put(trandia(arg)), args=(que, resultado,))
    t.start()
    while t.is_alive():
        t.join(30)
        yield "#processing...#"
    
    yield que.get()
    
return StreamingResponse(director(), media_type='text/event-stream')
