Hi,

I’m developing a Forge app in my Ubuntu WSL2 Environment.  
But when I run `forge tunnel`, I got this error:

Could you please give me some suggestions?

Hi @nhac.tat.nguyen,  
Thank you for reaching out. It seems like a failure with the local port it is trying to connect. Could you please re-try with `forge tunnel --verbose` which will give more details ? Re-try will pick a different port and may resolve the issue as well. If not could you please provide the forge cli version, docker version and also node version in your setup.

Hi @LashaniPerera, thanks for answering.

The screenshot in my post is the content from `forge tunnel --verbose`.

The versions I’m using:

- Forge CLI: `2.0.6`
- Docker: `20.10.12, build e91ed57`
- Node: `16.13.1`
- Ubuntu: 20.04 LTS running in WSL2

Thanks

Hi @nhac.tat.nguyen,

Is ngrok currently whitelisted in your environment? It requires the connection to be established and kept alive for tunnel to work.

Cheers

Hi @heinzen, I tested by running `ngrok http 8080` from my shell and it doesn’t work. So it looks like the problem is with `ngrok` and our network.

I will investigate more on this.  
Thank you for your help.
