Hi, check out the documentation troubleshooting. You have missed a step of adding an authorized redirect url (the url in the error message needs to be added). See the screenshot in the instructions and put literally what it says. (Some people think it means their instance url but it doesn't)

Thanks. I added it. I was using the older version that on had my nabucasa url in the redirect url
