Google Analytics Dashboard won't authenticate

I finally got Google Analytics to authenticate (using Chrome Incognito). Now I’m back to the earlier problem.

I reinstalled Google Analytics Dashboard. Now there is a new column in the Posts and Pages list – “Analytics”. For each post, the entry is “You need to log in and select an account in the options panel.”, with a link to the Google Analytics Dashboard Options.

The option to login to Google Analytics via Google’s OAuth takes me to a non-existent page – https://support.google.com/a/answer/6224347?p=oauth&rd=1

The other option is to use the older (not recommended ) authentication via user name and password.

This doesn’t work either.

Any ideas?
