How can I view console logs in Ngrok? - ngrok

I am creating an ngrok server using the command: ngrok http 2567
In my application i'm doing various console.log calls and I'd like to be able to view them!
I have tried using ngrok help and using the --log flag, but with no luck.
How can I view my logs when hosting on ngrok?

If you want to see the log from ngrok you should use localhost:4040, there is a list from all the requests you have done.

Try running command: ./ngrok <http/https> <port_number> --log=stdout
Ex: ./ngrok http 8080 --log=stdout
Worked for me.

Use following command with > ngrok.log & to output ngrok logs into one file named ngrok.log (You can rename accordingly based on your need):
ngrok <http/https> <port_number> --log=stdout > ngrok.log &
After that, open ngrok.log to see logs details.

unable to acaess the application in localhost through saucelabs tunnel

I am using Saucelabs to test my application on Mac, chrome configuration as I am using windows machine.
As per Saucelabs documentation, downloaded the Saucelabs Connect Proxy. Extracted the file and went to bin folder in command line and executed the below command
bin/sc -u <sauce_username> -k <sauce_accesskey> -x <sauce_data_center> -i <tunnel_id>
I got the message on the command line as "Sauce Connect is up, you may start your tests." Showed one tunnel is active on the SauceLabs my account under tunnel tab.
I started the session by going to Live --> Crossbrowser; selected the tunnel, localhost application url, browser(chrome 90) and Mac-Sierra and Start Session
Opened the application but it didn't show the feature which are on localhost.
Anyone, please help me on this, is there anything wrong i am doing in the proxy connection, because the same is working fine, if i directly open the application url on my windows machine with chrome.
I found the answer in the sauce labs documentation itself. The problem i am getting is related to SSL and here the solution.
If you don't want any domains to be SSL re-encrypted, you can specify all with the argument (i.e., -B all or --no-ssl-bump-domains all)
Now when run the below command to start the tunnel it resolve the issue.
bin/sc -u <sauce_username> -k <sauce_accesskey> -x <sauce_data_center> -i <tunnel_id> -B all

Proxy authentication using wget on cygwin

My institute recently installed a new proxy server for our network. I am trying to configure my Cygwin environment to be able to run wget and download data from a remote repository.
Browsing the internet I have found two different solutions to my problem, but no one of them seem to work in my case.
The first one I tried was to follow these instructions, so in Cygwin:
cd /cygdrive/c/cygwin64/etc/
nano wgetrc
at the end of the file, I added:
use_proxy = on
http_proxy=http://username:password#my.proxy.ip:my.port/
https_proxy=https://username:password#my.proxy.ip:my.port/
ftp_proxy=http://username:password#my.proxy.ip:my.port/
(of course, using my user and password)
The second approach was what was suggested by this SO post, so in my Cygwin environment:
export http_proxy=http://username:password#my.proxy.ip:my.port/
export https_proxy=https://username:password#my.proxy.ip:my.port/
export ftp_proxy=http://username:password#my.proxy.ip:my.port/
in both cases, if I try to test my wget, I get the following:
$ wget http://www.google.com
--2020-01-30 12:12:22-- http://www.google.com/
Resolving my.proxy.ip (my.proxy.ip)... 10.1XX.XXX.XX
Connecting to my.proxy.ip (my.proxy.ip)|10.1XX.XXX.XX|:8XXX... connected.
Proxy request sent, awaiting response... 407 Proxy Authentication Required
2020-01-30 12:12:22 ERROR 407: Proxy Authentication Required.
It looks like if my user and password are not ok, but I actually checked them on my browsers and my credentials work just fine.
Any idea on what this could be due to?
This problem was solved thanks to the suggestion of a User of the community AskUbuntu.
Basically, instead of editing the global configuration file wgetrc, I should have created a new .wgetrc with my proxy configuration in my Cygwin home directory.
In summary:
Step 1 - Create a .wgetrc file;
nano ~/.wgetrc
Step 2 - record in this file the proxy info:
use_proxy=on
http_proxy=http://my.proxy.ip:my.port
https_proxy=https://my.proxy.ip:my.port
ftp_proxy=http://my.proxy.ip:my.port
proxy_user=username
proxy_password=password

Setting up ngrok an homestad

I am trying to setup ngrok on my homestead, but it is not opening my project.
I have run ngrok http 80 and copied the address in forwarding part of the output to my Homestead.yaml file to map it to my project, and ran vagrant provision after that:
Forwarding http://92832de0.ngrok.io -> localhost:80
Forwarding https://92832de0.ngrok.io -> localhost:80
But when I open the http://92832de0.ngrok.io in the browser it opens up ngrok page "It works" and not my project.
When I have changed the port to ngrok http 8000 then I get Laravel error message:
Whoops, looks like something went wrong.
You can use any of your application which is in homestead.
For that, you need to run the below command by replacing 'your-site.app:8000'
ngrok http -host-header=rewrite your-site.app:8000
Before that, you need to register into ngrok and install ngrok then use the authtoken that given in your account.
For more details, refer this https://ngrok.com/docs
This is how It worked for me:
1) I have downloaded the ngrok (https://ngrok.com/) on my Windows host machine and executed ngrok.exe.
It has opened a command line interface for me
2) I typed the following
ngrok.exe http 192.168.10.10 -host-header=homestead.test
And it gave me the link of where to go:
Forwarding http://123456.ngrok.io -> http://192.168.10.10:80
Forwarding https://123456.ngrok.io -> http://192.168.10.10:80
I just went there ans saw my local environment Laravel Project.
You can add a function like this to your ~/.profile or ~/.bash_profile script on the host machine:
rock(){
ngrok http 192.168.10.10:80 -host-header=$1
}
After that you can use it to proxify any site on your Homestead machine like this:
rock your-site.app:8000
If you have multiple sites on your homestead you have to:
ssh into your homestead.
run this command: share yoursite.test
and that's it.
In homestead ngrok is already installed by default,
You just need to create an account from ngrok at https://dashboard.ngrok.com/signup
And then run:
vagrant up (in folder Homestead)
vagrant ssh
cd to/your/project/proyect
ngrok authtoken your__ngrok__account___token
share yourproject.test

How to generate fixed url with ngrok

I am working on facebook messenger.
Facebook app only accept one url for webhook but ngrock is generating new URL every time. Now I am unable to test my app because of webhook URL changed.
UPDATE May 2020
Serveo is up and running again! No installation, no signup!
All you need to do is to run this:
ssh -R <unique subdomain>:80:<your local host>:<your local port> serveo.net
like
ssh -R youruniquesubdomain:80:localhost:8000 serveo.net
UPDATE January 2020
Since there are some issues with Serveo and localtunnel, I want to share with you another free ssh-based self-hosting service: Localhost.run
Unfortunately, it does not provide unique subdomains but it is ssh-based so you do not have to install additional applications. Still waiting for Serveo coming back.
UPDATE April 2018
I've found Serveo just now! And it is totally incredible!
UPDATE November 2017
Probably, it is not the best option for you but I started using localtunnel instead of ngrok.
An installation and run flow is very simple:
npm install -g localtunnel
lt --port <your localhost port> --subdomain youruniquesubdomain
Then I can go to my http://youruniquesubdomain.localtunnel.me
That's it!
No more free subdomain support from ngrok.....pls have a error as below
Tunnel session failed: Only paid plans may bind custom subdomains.
Failed to bind the custom subdomain 'arvindpattartestfb.ngrok.io' for the account 'arvccccc'.
This account is on the 'Free' plan.
Upgrade to a paid plan at: https://dashboard.ngrok.com/billing/plan
ERR_NGROK_313
You need to set up auth token. You can find it here https://dashboard.ngrok.com/auth. (W̶o̶r̶k̶s̶ ̶w̶i̶t̶h̶ ̶f̶r̶e̶e̶ ̶v̶e̶r̶s̶i̶o̶n̶,̶ ̶n̶o̶ ̶n̶e̶e̶d̶ ̶t̶o̶ ̶p̶a̶y̶ it's now paid feature, see ngrok pricing).
Then you can use it like this:
ngrok http 80 --subdomain yoursubdomain
Neither localtunnel.me or Serveo are working for me right now so I created a temporary solution that works for some use-cases including mine (react-native local development): using the ngrok npm package one can save the generated ngrok url into a json file, and that file can be read for any other app.
First make sure to install ngrok using npm install ngrok then use this node script:
const ngrok = require('ngrok');
const fs = require('fs').promises;
(async function() {
const url = await ngrok.connect(3000);
const api = ngrok.getApi();
let data = await api.get('api/tunnels');
data = JSON.parse(data);
let dict = {'domain': data.tunnels[0].public_url}
await fs.writeFile("config.json", JSON.stringify(dict));
console.log("saved " + data.tunnels[0].public_url);
})();
Then from your app you may read it using code similar or equal to:
const backend = require('./config.json').domain;
For DHIS2 local installation, I did this on the terminal on ubuntu server.
Make sure your web is running on the specified port. Mine was on 8080.
ssh -R dani.serveo.net:80:localhost:8080 serveo.net
The beauty of this serveo.net is you can reuse the same hostname prefix url before serveo.net as many time as you want, even if power goes off or internet diconnection.
Staqlab tunnel is providing domain for free. Its works great but need a binary to be downloaded from there website. Using this service for month without any hassle
In 2022 (almost 2023) pagekite.me works for me.
It is very similar to ngrok, and requires the installation of pagekite.py (and, obviously Python).
After installation click on pagekite.py opens pagekite shell.
Run command: 8080 subdomain.pagekite.me
I noticed that no one mentioned how to have static ngrok urls, which was the main question about.
A way to do it is to edit the ngrok.yml file, which is located at
Linux: "~/.config/ngrok/ngrok.yml"
MacOS (Darwin): "~/Library/Application Support/ngrok/ngrok.yml"
Windows: "%HOMEPATH%\AppData\Local\ngrok\ngrok.yml"
You can have content such as:
version: "2"
authtoken: valid_auth_token
tunnels:
first-app:
addr: 3000
proto: http
hostname: yourfixedngrok_id1.ngrok.io
second-app:
addr: 8000
proto: http
hostname: yourfixedngrok_id2.ngrok.io
This will help you expose multiple ports, and have a persisted url for each of which based on the value you set for hostnames.
After that, you run your ngrok using this command:
ngrok start --all
Though its not a solution but take it as workaround, I had the same problem while testing. What i did is keep the ngrok running with my http port, so my ngrok url is not changing. but I frequently changing and restarting my server for testing and debugging.

Stop sharing a port on Ngrok

The Ngrok documentation mentions this example to share a local port on Internet.
Example: Open port 80 on your local machine to the internet
$ ngrok 80
How do I stop sharing this port if I would not want it to be accessed on the internet any more>
On windows machine go to command prompt:
taskkill /f /im ngrok.exe
killall ngrok from a script or the command line will kill all running ngrok tunnels that are running.
This is what worked for me. Ty #kkron.
First, you have to find the ngrok process id by $ top command.
After that, just run $ kill -9 {ngrok_id}
That's all :)
Stopping the ngrok port/tunnel
Simple Solution
If you are running ngrok normally, then use Ctrl+C (On Windows) or Cmd+C (On Mac) in ngrok command line.
(Check below if issue still persist)
Extended Solution
If the port does not stop/close normally or there are active ngrok sessions that are not responding, then use: killall ngrok
If the above does not work or the port is still running,
Fix ngrok in your system by setting up your auth code again by logging into https://dashboard.ngrok.com/get-started
Generate a new token on the dashboard (scroll down dashboard) to https://dashboard.ngrok.com/get-started/your-authtoken
Click on "reset authtoken", copy the auth-code, then go-to ngrok on command-line ngrok authtoken INSERT-YOUR-NEW-TOKEN-HERE
Then go to ngrok folder or use command line to delete the .ngrok configuration file and directory: ngrok.yml, to remove the old configuration effectively ending all the open ports, tunnels and sessions.
Simple as pressing ctrl+c. But I'm not sure if it closes any ports. The same happens as #user7032676 told.
You just have to stop ngrok for this.
Quick search process with grep
top | grep "ngrok"
My id was this, make sure to change with yours
kill -9 55636
If you like start again tunneling from working directory
ngrok http 3000
You should see (CTRL+C to quit) on the top right corner of your terminal, when you are running a ngrok session (Online).
Although in my case, CTRL+C wasn't working. Instead CTRL+ALT+C did the quitting for me.
Operating System: Ubuntu 20.04
For some reason whenever I launched the ngrok agent on windows, the terminal will shutdown and not stay open. I would have to go to the website to see the url for the website.
To shut it down I could not do ctrl-c. I simply went into task manager and deleted the process.
To access the task manager on windows do ctrl + alt + delete
Reboot the computer and all. Hope helped
