Seeing <urlopen error timed out> consistently on sandbox.

[msaparito]

Running bulk uploads for offline conversions to sandbox for testing an environment's connectivity and noticing that once we enter the example code:

File: bulk_offline_conversions.py Line: 38

        download_entities=write_entities_and_upload_file(
            bulk_service_manager=bulk_service_manager, 
            upload_entities=upload_entities)

The fault occurs. We know our refresh_token, client_id, developer_token should be fine as we manually request a new refresh token in our pipeline prior to this. 2 days ago we did not receive this error, we are just trying to see if it's the sandbox or not.

Our stack output:

Loading the web service client proxies...
-----
Applying offline conversions...
<urlopen error [Errno 60] Operation timed out>

I have the same issue when trying to publish a responsive search ads to sandbox account.

add_ads_response=self._campaign_service.AddAds(
                    AdGroupId=row['ad_group_id'],
                    Ads=ads
                )

I have checked and production entries run as expected. I assume this is an error with sandbox's endpoint.
