For errors mentioning that you need to "re-authenticate" you can usually resolve the issue by following the steps below. 

Use private/incognito browsing to re-authenticate. 

• Open a new window

  • Google Chrome: Go to the top-right corner, select the menu icon (3 dots button) and choose New Incognito Window.

  • Firefox: Go to the top-right corner, select the menu icon (3 lines button) and choose New Private Window.

  • Microsoft Edge: Go to the top-right corner, select the menu icon (3 dots button) and choose New Private Window.

• Sign In

  • In this window, go to sundancetv.com  as usual

  • Sign In and choose your provider.

  • It should require you to sign in manually, instead of auto-filling the fields.

This should take care of the "re-authenticate" message, and in the future you should be able to visit sundancetv.com in a regular window.

Please try the process above that applies to you. If you're still having trouble, please submit a support ticket and tell us more about your situation.
