Nst manager login credentials error

After deleting my nest thermostat and most manager… I reinstalled everything and when I go to login nest credentials it will allow me to put in the info and ciick accept. After that. Nothing happens

If you check out the NST Manager thread, you can find out they are out of tokens. You will need to create a Nest Developer Account and create your own token. It is in the wiki which you can find at the top of that thread.
