Error when Using Bulk Download Service

I have been working on a Python script that pulls data from the API using BulkServiceManager through the v13 Bing Ads SDK. On Friday, it stopped working with the following error:

urllib.error.URLError: <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

At first I thought I had caused this with other changes I had made since the previous day but the error persisted after I checked out a commit that I knew had been working before. So I hoped it was just something temporary and decided to check it out today to no avail.

I decided to try it out on another computer and it ended up throwing the following error instead:

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Any help would be greatly appreciated. I'm not really sure what information would be needed to get to the bottom of this but let me know and I'll happily provide it.
