Journey task (Learn enrollment) - "An error occurred while loading the content from content server"

I am having an issue with the learn enrollment task type in an Onboarding Journey. When the employee tries to access the learning content from the Journey, they can click launch to open the learn enrollment but the message "An error occurred while loading the content from content server" keeps appearing. I have ran scheduled process, validated rich text media, checked profile options, and confirmed that there is an offering attached to the course. The issue still persists and I am trying to avoid raising an SR unless I absolutely have to. I will attach a screenshot of the error
