404 Error when connecting google account

I’m not sure if this is a bug or if I’m doing something wrong, but when I enable the plugin and click “Sign In”, it prompts me to connect to my Google account and choose which account to use. Then it asks me to accept the permissions, which I do, but it throws a 404 “Page Not Found” error. If this is a bug, can you fix it, if it isn’t, can you help me figure this out? Ive attached the steps i take below. Any help would be awesome, thank you in advance.
