Well, of course I find a solution shortly after posting the question. In case someone else encounters this same issue... I had both the Google Home iOS app and the Google Assistant iOS app installed on my phone. When I clicked on the Home Control section in Google Home, it kicked me off to the Assistant app to finish the linking process. This is where the authentication failure happened. I uninstalled the Assistant app and tried again. This time the Google Home app pulled up the ISY Portal login page. Entering my credentials there worked correctly.

Hi, I'm subscribed to ISY Portal and had to unlink my account from Google Home because I added a couple of new devices that were not showing up. I tried to re-link my Portal account through the Google Assistant app, but when I enter my email and password for ISY Portal, I get an error page showing code 401, "Your client does not have permission to the requested URL." I can log in directly to the ISY Portal using the same credentials. How can I resolve this issue? Thanks!
