vRB 7.1 - Business Management Tab keeps loading and no content

I have registered the vRB for cloud (7.1) to vRA 7.1. Permission has been assigned to view the Business Management Tab (Business Management Administrator).

When I click on the Business Management tab, it keeps loading. Also, if I click on Administration >  Business Management, it keeps loading too.

I have done the followings:

1. Update the Time Settings - All servers time are in sync (Less than 10 secs difference)

2. Restart all servers

3. Re-register the vRA in vRB Appliance

4. Clear browser cache

However, it is still not loading at all.
