HTTP Error 429 on Linux server, but not my local machine?

I’m running a Python program that downloads one single video from YouTube every hour using Pytube onto my local machine and I have no problems with it at all. However, when I deploy the same program onto my Linux server, I receive the following error:

urllib.error.HTTPError: HTTP Error 429: Too Many Requests

Does anyone know why this is or what I can do to fix it? I’m using a Linode Shared CPU running Ubuntu 21.10.

Here is the full error:
