Problem reconnecting within script 403 Client Error: Forbidden for url: http://xxx.xxx.x.xx/app/request?seq=1161143374

Hello, I wrote a script that control a lamp color based on the decibel levels measured by a microphone. I'm using it to help customers of a winery out of my windows to control the loudness of their voices. The script runs automatically every night in a raspberry pi. To deal disconnections and reconnections I added to the script a function that goes like this

connection=False
def connect_lamp():
    try:
        global l530sec
        l530sec = PyL530.L530("xxx.xxx.xxx", "me@mymail", "mypassowrd")

        l530sec.handshake() #Creates the cookies required for further methods
        l530sec.login() #Sends credentials to the plug and creates AES Key and IV for further methods
        global connection
        connection=True
    
    except Exception as e:
        #print(e)
        connection=False
        return
    
while connection==False:
    connect_lamp()

This function work perfectly if the lamp is offline when the script is started, but if the connection is lost afterwards it give the 403 Client Error: Forbidden for etc..
I can share the entire script here or on my github, any suggestion will be greatly appreciated, having this script running properly is of vital importance!!

Thank you very much
