Question / Help Please help a new Linux user

[starseed-pl]

I am trying to learn how to stream my games and my art on twitch. I seem to be fine but all of a sudden I get a random notification that displays 'Network Disconnected' and “Network service discovery disabled. Your current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled.”

I am running Ubuntu MATE 18.04.2 LTS

Please let me know what info you need. I'm so lost and I just want to stream so my daughters can watch me play when we are away from each other.
Thank you so much for your time.
