I'm developing a Telegram bot and want to use ngrok to receive messages from the webhook.
Setting a webhook works. When I set my publicly reachable domain as URL, I actually get the expected messages. Now, when I know, that the code is working, I want to tunnel messages from the ngrok server to my local VM.
$ ngrok http telegrambot.sandbox.loc:80
ngrok by @inconshreveable (Ctrl+C to quit)
Session Status online
Session Expires 7 hours, 59 minutes
Version 2.2.8
Region United States (us)
Web Interface http://127.0.0.1:4040
Forwarding http://0955b8f3.ngrok.io -> telegrambot.sandbox.loc:80
Forwarding https://0955b8f3.ngrok.io -> telegrambot.sandbox.loc:80
Connections ttl opn rt1 rt5 p50 p90
0 0 0.00 0.00 0.00 0.00
Well. Now I set the webhook and get a response like
{
"ok":true,
"result":{
"url":"https://a200f5f7.ngrok.io",
"has_custom_certificate":false,
"pending_update_count":0,
"max_connections":40
}
}
ngrok's CLI output:
HTTP Requests
-------------
POST / 502 Bad Gateway
POST / 502 Bad Gateway
POST / 502 Bad Gateway
POST / 502 Bad Gateway
I didn't get any messages rewarded. Then I added the host name to the /etc/hosts:
127.0.0.1 telegrambot.sandbox.loc
Now I'm getting
HTTP Requests
-------------
POST / 405 Not Allowed

How to set up and use ngrok correctly and get messages from a Telegram bot forwarded to a local system?
Additional info:
I also tried to get ngrok working on my publicly accessible server. The domain is SSL protected and I don't need this forwarding for the productive system. I just wanted to see, how/whether It would work.
ngrok http mybot.myserver.com:80
Output:

The result (both, with and without the /etc/hosts entry) seems to be OK:
HTTP Requests
-------------
POST / 200 OK
POST / 200 OK

POST / 200 OK
But the defined URI seems still not to be triggered.
You may try this:
ngrok http telegrambot.sandbox.loc:80 --host-header=telegrambot.sandbox.loc
