I used gnome-network-displays for sometimes and think it's a very good software. before this I tried intel/wds and miraclecast but cant make them work. They all want me to stop wpa_supplicant.service and NetworkManager.service and I feel not good . Only when I use gnome-network-displays I successed to put my pc screen to the tv. But suddenly it can't work.....
So may someone can tell me how to solve this or how to debug... THANKS!
This is log:

Could it be that a firewall is blocking access from the TV to port 7236 on your machine?
