Why doesn't dropbox.com or box.com Authenticate with my forms?

Hello

I keep trying to integrate dropbox or box with my forms so that my users can upload videos, songs, and docs to my dropbox.

After I allow the service to link with jotform the message below occurs when trying to move to the next screen 

It wil not integrate and I need this to be able to finish the forms because the members have to upload the media files.

Please help asap

We apologize for any inconvenience but i'm unable to reproduce the issue on my end. Kindly try clearing your browsers cache or using a different browser and see if the helps.
