How to Troubleshoot and Fix Issue Playing Lesson Videos on Kubicle
Why it happens: Most video playback errors are caused by VPNs, network firewalls, or browser extensions blocking the video stream.
Quick Fixes:
-
Kill the VPN: Disconnect any VPN and refresh.
-
Incognito Mode: Open the link in a private window to bypass ad-blockers or bad cache.
-
Swap Browsers: If using Safari or an older version of Edge, try Chrome or Firefox.
-
Switch Networks: If on a strict work Wi-Fi, try a guest network or personal hotspot.
When to escalate: If your VPN is off and still experiencing issues, your IT team may need to "whitelist" these domains:
-
*.mux.com
- *.litix.io
- *.kubicle.com
