Ngrok错误'502坏网关' [英] Ngrok errors '502 bad gateway'

问题描述

使用任何类型的Web App的东西都很新，我一直在尝试慢慢构建一个Facebook Messenger Bot。当我尝试使用ngrok时，我无法访问我给出的地址，即：

  ngrok http 5000 
  

是我在命令行中输入的内容，它将返回此信息：

  ngrok by @inconshreveable 
 
会话状态在线
版本2.1.18 
地区美国（us）
 Web界面http://127.0.0.1:4040 
转发http://ea986ca5.ngrok.io  - > localhost：5000 
转发https://ea986ca5.ngrok.io  - > localhost：5000 
 
连接ttl opn rt1 rt5 p50 p90 
 0 0 0.00 0.00 0.00 0.00 
  

但当我将地址' https://ea986ca5.ngrok.io '作为Facebook开发人员的页面要求：

 与http://ea986ca5.ngrok.io的连接已成功通过隧道连接到您的
 ngrok客户端，但客户端未能建立到本地
地址localhost：5000的连接。 
 
 
确保webhost服务在localhost：5000上运行，并且它是一个
的有效地址。 
 
 
遇到的错误是：拨打tcp [:: 1]：5000：connectex：没有连接
因为目标机器主动拒绝了它。 
  

我的本​​地端口有问题吗？谢谢！

解决方案

这对我有用

ngrok.exe http -host-header =重写localhost：

例如ngrok.exe http -host-header =重写localhost：5219

<我正在使用visual studio 2017，不知道它是否会影响anthing。

Quite new to using any sort of Web App stuff, and I've been trying to slowly build a Facebook Messenger Bot. When I try to use ngrok I can't visit the address I'm given, i.e:

ngrok http 5000

is what I'm putting in the command line, and it's returning this:

ngrok by @inconshreveable

Session Status                online
Version                       2.1.18
Region                        United States (us)
Web Interface                 http://127.0.0.1:4040
Forwarding                    http://ea986ca5.ngrok.io -> localhost:5000
Forwarding                    https://ea986ca5.ngrok.io -> localhost:5000

Connections                   ttl     opn     rt1     rt5     p50     p90
                              0       0       0.00    0.00    0.00    0.00

But when I take the address 'https://ea986ca5.ngrok.io' as is required by the Facebook developer's page, it says:

The connection to http://ea986ca5.ngrok.io was successfully tunneled to your
ngrok client, but the client failed to establish a connection to the local  
address localhost:5000.


Make sure that a web service is running on localhost:5000 and that it is a 
valid address.


The error encountered was: dial tcp [::1]:5000: connectex: No connection 
could be made because the target machine actively refused it.

Is it a problem with my local port? Thanks!

解决方案

This worked for me

ngrok.exe http -host-header=rewrite localhost:

e.g ngrok.exe http -host-header=rewrite localhost:5219

Im using visual studio 2017 dont know if it effects anthing.
