If you find yourself repeatedly being booted out of a Samba Live meeting, it's highly likely that there is an issue related to your internet connection.
Typically, this is a firewall in the router or some other sort of connectivity issue.
Please contact your internet provider or, if you're at work, your IT support team, to help you diagnose this issue.
Pro Tip: try signing in through a VPN in order to test out your connection. If you don't get booted out of the meeting while logged in to a VPN connection, the issue is likely a firewall restriction with your original, non-VPN connection.
