Why isn't the video starting or why does it keep buffering?
The cause can be the event rendition, device, VPORT client, browser, or network. VPORT does not publish fixed 25/50/100 Mbps guarantees for its playback modes.
Follow Video keeps buffering or won't start for the current troubleshooting steps. Trying another event is especially useful: if other events work, include that fact when reporting the affected event.
If the problem continues, open a conversation in VPORT Support with the event, approximate time, device, operating system, browser or VPORT version, network type, and screenshot or recording of the error.
