I am trying to integrate my Salesforce CRM Account with my Salesforce Marketing Account.

I am following steps that are given in the Trailhead: Marketing Cloud Connect. https://trailhead.salesforce.com/content/learn/modules/marketing-cloud-connect/finish-mc-connect-configuration

While performing the steps under section "Connect to Marketing Cloud Within Salesforce CRM", I am getting the below error when I trying to connect my Marketing Cloud Account via Salesforce CRM

Error: authorizationCode cannot be null.
