问题
I'm new to react native and I'm trying to start my react-native application using expo. But the tunnel option is not starting, it's displaying the
Tunnel URL not found, falled back to LAN URL.
When I click to the tunnel tab, because it's not yet started. I waited for 2 hrs for it to start but it won't start. I run through different issues and questions asked but none solved my issue. 
ENV:
"expo": 36.0.0,
"expo-cli": 3.11.7
Does anyone know how I can solve this?
回答1:
Try expo-cli start --tunnel, it's Working for me.
