Please wait when enrolling device

After installing TRASA sucessfully and accessing the web console, there is an issue with the enrollment of mobile device.
While on “Part 1 - Setup TRASA server and root account” followed the steps of changing root password and next enrol device and after getting TRASA Authenticator the next step was scanning the QR code,but it kept circling and saying please wait.I tried both validation methods from the App Store and Google Play.What should I do in this situation? Can try skipping the device validation step?
