Web Reader connectivity

I have been trying to setup a Classroom Dashboard for each of my Engineering Classes within 3dExperience (Following the suggestions in the video that was put out to teachers about setting up the platform as an LMS).Web Page Reader will not connect with my Classroom Resource Website at https://sites.google.com/view/engineeringtech2podcasts/home this resource page houses all the links and podcasts for my students to access to complete their assignments.I get the error "sites.google.com refuses to connect".Is there a setting withing 3DExperience that I need to adjust?Dr. B
