Cannot run script due to login forbidden 403 error

[Cally99]

Thanks for uploading this script. It's exactly what I'm looking for, However I'm having an error running the script with my login details

I looked at a workaround with instaloader saving a session token and being logged into instagram on firefox but your script doesn't work
Do you know why? Thanks
/venv/lib/python3.9/site-packages/instaloader/instaloadercontext.py", line 226, in login
raise ConnectionException("Login error: JSON decode fail, {} - {}.".format(login.status_code, login.reason))
instaloader.exceptions.ConnectionException: Login error: JSON decode fail, 403 - Forbidden.
