MagicSchool's professional development courses are hosted on Skilljar, with training videos embedded via Clueso. If you or your users are unable to load courses or videos, a network content filter is the most common cause.
⚠️ Common Symptoms
Course page loads but the video area is blank or shows a broken file icon
Videos load on a personal device or home network but not on a school device or network
The course platform itself is inaccessible or returns an error page
📝 Note: If content loads on a personal device or mobile hotspot but not on your school network, your district's content filter is almost certainly the cause.
🛠️ Resolution Steps
Step 1: Test on a Different Network
Ask the affected user to try accessing the course on a personal device or mobile hotspot. If it loads there but not on the school network, proceed to Step 2.
Step 2: Whitelist the Required Domains
Your district's IT administrator will need to allowlist the following domains to allow course content to load on school devices and networks:
Skilljar (course platform): *.skilljar.com
Clueso (embedded training videos): watchclueso.com
⚠️ Important: Whitelisting must be done by your school or district IT administrator. Teachers and students cannot make these changes themselves.
Step 3: Verify and Test
Once IT has made the updates, ask the affected user to refresh the course page on their school device. The videos should load normally.
