Optional steps

4. Use ngrok token

As oper ngrok site. Running this command will add your account's authtoken to your ngrok.yml file. This will give you more features and all open tunnels will be listed here in the dashboard.

$ ./ngrok authtoken My_Token_from_ngrok.com

Disclaimer

My personal recommendation is to use this tool for experimental and personal projects. Therefore, I use Google Cloud Shell Project from GMail personal account that has no connectivity with any production environment, therefore it's not prone to any security issues.

any update on this issue

Hey! Can I ask you a question?
When I run ngrock, I see Permission denied errors.
I used 'chomd 777' in my home directory, but I can't.
What should I do?

I faced same issue
