Failed to authenticate. Please check your credentials again.

I installed the Account Engagement WP plugin. I then created a SalesForce Connected App and received the consumer details. I then filled in this information on the Account Engagement WP Settings screen. I then clicked on the Authenticate with SalesForce button. It gave me the error message “Failed to authenticate. Please check your credentials again.” I have tried it several times and it did not work. I cleared the cache and reset the settings. It still would not authenticate. I also made sure the Oauth scopes had the following:

• Access Pardot services (pardot_api)
• Perform requests on your behalf at any time (refresh_token, offline_access)

Lastly, I made sure the policy level (In my connected application) and were set to have the?Permitted Users?to?Admin approved users are pre-authorized.

Please help.

Thank you.
