If you're having trouble with SCORM files not loading properly in TalentLMS, then it's likely you've added the wrong domain to your Allowlist.
Talent LMS don't actually use your unique domain to load SCORM files (e.g. myname.talentlms.com), they're using a generic URL for all of their customers (https://cdn.talentlms.com).
To ensure SCORM will load correctly, make sure you add the following URL to your allowlist: https://cdn.talentlms.com
