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:

While testing this script, and using smaller CSVs (with less records to read in), I never had an issue. Just recently has this been occurring. Any help is greatly appreciated.
