After doing some more reading on this forum it looks like one option is to add the following to lms.conf.
/home/tutor_installation/.local/share/tutor/env/apps/nginx/lms.conf
add_header X-Frame-Options "ALLOW-FROM www.wyworx.com";
add_header Content-Security-Policy "frame-ancestors www.wyworx.com";
I stopped and restarted Tutor and it now renders the content on the iframe.
I thought I should post this solution in case anybody runs into a similar issue.
