Won’t connect to new network

I’ve changed my wifi and my ring chime pro and ring doorbell will not connect. It’s ring doorbell 4, I’ve fully charged the battery and it still won’t connect.My router is near the doorbell and in the same position as my previous one. I’ve even tried to uninstall the app and start again. I’ve followed all steps suggested through the support pages but nothing is working. Is there anything else I can do? Thank you
