rails devise 401 unauthorized for a specific page

I'm having trouble discerning why my app is returning a 401 Unauthorized. Other actions in my Institutions controller are working just fine while not signed in. However, this and another page are returning 401. If logged in, these pages work perfectly fine, but they shouldn't require being logged in. I have even gone so far as to empty the view and the action, but still the page is returning a 401. When debugging through fiddler, I simply receive a 302 Redirect. I've tried researching elsewhere and have tried the solutions from Warden authentication recalls 401 Unauthorized without success.
