Tunnel URL not found, falled back to LAN URL

For these past 1-2 weeks, I cannot seem to run the expo client on the tunnel. The output when I run

> expo start --tunnel
Output:

Tunnel URL not found (it might not be ready yet), falling back to LAN URL.
Tunnel URL not found (it might not be ready yet), falling back to LAN URL.
Tunnel URL not found (it might not be ready yet), falling back to LAN URL.
Tunnel URL not found (it might not be ready yet), falling back to LAN URL.

Things I have tried:

  1. Using different networks: University campus wifi, the hostel wifi, home wifi and my 4G hotspot.
  2. Logging into expo client before running expo start

Please I need help urgently, as I’m using expo for my school’s project. Thank you!

I’ve had this issue after I grabbed the lastest expo-cli, 3.15.5. I believe there’s a problem with the latest release and reverted back to
expo-cli 3.11.9
node 12.14.1

Try nvm install v12.14.1, it installed the version of expo-cli listed above in one command. I have see a very instances where the tunnel still doesn’t come up. Ctrl-C to the instance of your bundler and bring it back up with expo start should do the trick.

Can confirm reverting to expo-cli@3.11.9 works. Tried all the versions after it, and no dice. I’m on node v13.11.0 on WSL2/Ubuntu 18.04.4.

I have the same problem here, everything was working perfectly until today.

An other problem, when I scan the QR code with an iPhone, I get this problem : “no data available for this QR code”

I created new terminal window and ran the command expo publish in the same directory. Then I restarted with expo start and everything works fine.
