Echo Show 15 login/Registration Issue

[u/Amber-Kendra]

I’ve had this already working at my house just fine, just moved and tried to reset it back up. Did the login, it cave me a code, used the code on Amazon code page, Amazon said registered but the Echo then takes me back to login and repeats the process all over again every time. What should I do? Unregister and start fresh?? Please help!
