A. Check your Wi-Fi connection by testing it with other apps or websites. If they work fine, try resetting your router. Unplug it for about 10 seconds and then plug it back in. Once the router is back online, reconnect your iPhone to the Wi-Fi and try going LIVE again.
B. If the issue persists, switch to mobile data temporarily to see if you can go LIVE. If it works on mobile data, the problem may be with your Wi-Fi network settings. Consider changing the Wi-Fi channel in your router settings or contacting your ISP for assistance.
