Problem
If your browser is configured to block third-party cookies, HxGN SDx2 tries to authenticate repeatedly.
Solution
Most browsers have a configuration setting that you can select that blocks any third-party cookies. For example, in Microsoft Edge® it is located in Settings > Site permissions > Cookies and site data. This setting should be switched off to allow the reading and saving of all third-party cookies from a site.
You can also add the site as a white-listed domain to allow the reading and saving of the cookies from that site. In this case, you should add the OAuth authentication server domain address to the list of allowed sites.
