How to add device v3+. Keeps saying problem

I had my system set up but somehow deleted it! Anyway had to set the whole home up again but now when I try adding my devices it won’t do it. Scans the barcode and I type in manually but when it states register it then comes to try again or support not adding devices ? Help
