[Python] Failed to establish a new connection: [Errno 11001] getaddrinfo failed' in Python 3.9

This script is used to send data to a 3rd party. It seems to run fine when connected to any network other than my work network. When connected to my work network, it will run for a few minutes, PUT/POSTing as it should, and then suddenly the following error will appear:
