I have been using AirPlay for years from my iPad to Samsung TV. Never any major problems. Now suddenly I get the message “unable to connect”. Updated iPas iOS to latest version. Disconnected TV and reconnected it. Nothing seems to work. Any suggestions?

As described, your LAN infrastructure may not be passing Apple Bonjour traffic on you local network - or your WiFi Router or Network Switch may be blocking this device discovery protocol.
The Apple Bonjour protocol uses mDNS (Multicast DNS) UDP port 5353.
If you have any VPN or Security Apps (e.g. Norton) installed on your iPad, these may need to be disabled or completely removed. These Apps can interfere with your iPad's network connection.
With offending Apps or services disabled, you may find that restart of your network components will resolve the problem. You’ll need to restart your network devices in the correct order. Assuming that you WiFi Router provides DNS services for your network, restart devices in this order - allowing time for devices to fully boot/restart prior to restarting other devices:

Reset AirPlay on the TV, ensure both devices are on the same Wi-Fi band, reboot the TV network module, and reset iPad network settings if needed.
It worked without any problems the last few years with VPN and Norton. So why suddenly, about 10 days ago, it stopped? Will disconnect and restart the components. Hope this works.
