auth.services.adobe.com refused to connect

The error has changed slightly after some troubleshooting by one of my colleagues when the user submitted a new request and they started working with them on it, but the workflow is essentially the same, the user attempts to create a new web form and submits an existing PDF file, tries to add signature fields and then when they hit next, they encounter a blocking message that says either "error auth.services.adobe.com refused to connect", or "Request e-signature services aren't available at this time."  However, the user can login with her boss' Adobe account on the same computer under the same user profile and do the same steps without an error.

Previously, after clicking on Create a Web Form, it took the user to a page where they could submit a PDF file and select which fields to add, then they would click Next and encounter the error.  Now it goes straight to the error when they click Create a Web Form.

The user in question already tried connecting from another computer on the same network and with a different web browser and have the same issue, however another user on the same network is not having this problem. No proxies, no firewall rules blocking outbound web traffic. System date/time is correct and centrally managed.
