I keep getting this error when I submit the REST auth code marketo sends to me.
"Looks like you changed locations since you requested an authorization code; try again"
I have tried this on two different computers. Any ideas?
Do you have a problem when you use the Identity endpoint to get an access_token the usual way?
Ah, that's good. I never use the UI way. (Couldn't figure out a case in which an expiring token would be useful to distribute to, say, an external partner. A permanent token, sure.)
Are you attempting to log into the instance using an API only role? Those are not meant for logging in via the UI - it should only be used for API calls. If you need to get into the Marketo application, you should make a separate user without the API only role.
