How can I resolve this:

"Error: Invalid Origin. Register your new client (site-to-temp-url.com) as a new Web platform on your project console dashboard" The message is vague, and couldn't find anywhere with good guide to help resolve

TL;DR

Issue: Developer needs to set up a new client on the project console dashboard but is receiving an "Invalid Origin" error message. Solution: Register the new client (site-to-temp-url.com) as a new Web platform on the project console dashboard.
