If you see messages like "Poor Signal" or "broadcast paused" during your EventLive stream, or if viewers report glitchy, stuttering, or buffering video, most likely your internet connection on location is not great.
If you are using Wifi, try switching to mobile data or another Wifi connection. The other option is to try moving closer to the router. Please keep in mind that WiFi can be very unstable depending on how far the router is located, how many people are connected to the same network at the same time, etc.
