Failed to load account.box.com/login/mfa during OAuth2

Hi, 

I integrated one of our apps with Box, one of the integration is OAuth2 connection. Our app will redirect the user to https://account.box.com/api/oauth2/authorize to perform OAuth2.  

The problem is sometime it redirects the user to https://account.box.com/login/mfa and display error “We could not load the verification page. Please try again.”, after the user have the stale box website open for awhile. I have uploaded the screenshot in https://app.box.com/s/vnbaev9m9kxqgzmowaq7agsuxovzjih9 (there are some problem with the image upload in this editor)

Clearing the browser cache can temporary fix the problem but it is not the correct fix as it breaks the UX & most of our users are from a non-technical background.

It would be great if someone can take a look at this issue as it can cause huge trouble for our non-technical user. 

Thank you and looking forward to hearing back.
