Dropbox cannot connect to NAS

I have a ReadNas 422 version 6.10.1. My Nas is unable to to connect to my Personal Dropbox account. Steps to recreate issue: 1. Log into my ReadyCloud Admin page, and click on the "Cloud" tab. 2. I click on the DropBox On/Off icon to turn it on. A pop up box then says: "ReadyNAS Cloud Storage would like access to the files and folders in your Dropbox" to which I click on "Allow". 3. It then says: "Redirecting your personal information to http: (gives my local IP which is correct) Please verify this is your NAS before proceeding. I click on Agree. 4. A new box pops up saying: "Redirecting please wait" for about 1 second and then closes the entire window down. Normally at this step, I SHOULD be able to choose which pathway and which folder I want it to sync with. I do NOT get that option. Trouble Shooting steps I have taken: 1. Rebooting manually, waiting 2 minutes and turning back on. 2. Using multiple browsers, including Chrome, Firefox, and IE 3. Tried multiple different sign ons for Dropbox 4. Going into Dropbox and removing access, and re-adding access. 5.I have also contacted Dropbox support, to which they have stated this issue appears to be with ReadyNAS. 6. I have enabled Google Drive on my NAS to which it works fine. Issue is only DropBox. Please help.
