ngrok error page: Failed to complete tunnel connection

Question

Please help me in resolving this issue.

Thanks

Answer 1

While I was working on a Rails app I wanted to run it on ngrok but I got same error below:

The connection to http://xxxxxx.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:3000.

It seems like ngrok works fine but my local server is not. Which is true since I forgot to run my rails app first by run $ rails s. By doing so I was able to get ngrok tunneing works fine.

Make sure your local server run first.

Good luck.

Answer 2

ngrok shows this error when the local server is not running start your server first and also check the server port as well as ngrok port

For example: i am using two servers WAMP && XAMPP WAMP is on port 80 While XAMPP is on port 8012

therefore the command will be

ngrok http 80 for WAMP folder ngrok http 8012 for xampp folder

Answer 3

I was getting that error even though my local server was running.

ngrok http -host-header=rewrite launch.local:80

It helped when I changed it to

ngrok http -host-header=launch.local 80

Answer 4

First start your local server before you running ngrok.

eg:- I start my local server via apache service apache2 start

Answer 5

The solution that worked for me: Try explicitly setting the localhost IP by using the command ngrok http 127.0.0.1:8000 (if you have an external server, you can do :port) instead of ngrok http 8000.
