I'm developing a Node App. I need https for receiving callback URLs from 3rd party Apps. So I added SSL certificate.
ngrok works only with http URL (http://localhost:3000).
I'm using the command ngrok http 3000. But when I access ngrok https URL, I'm getting 502 Bad Gateway error in browser.
How do I make ngrok work with https://localhost:3000 URL.
If you are using for signup or login with google/facebook then I can suggest you another way. You can use
https://tolocalhost.com/
configure how it should redirect a callback to your localhost. This is only for development purposes.
ngrok can itself provide https support - this is one of its major use cases (at least for me) so you don't need to create any ssl certificates
Step-by-step guide
Here's a simple testing file:
$ cat t.html
<body>
<h1>test</h1>
</body>
Bringing it up a simple http server on localhost:
python -m SimpleHTTPServer 7070
Running ngrok
$ ngrok http 7070
grok by #inconshreveable (Ctrl+C to quit)

I have created a node.js server, which listens to:
server.listen(process.env.PORT || 3000, '0.0.0.0');
I tried to create a docker container and run it on my ubuntu(20) server using this tutorial:
https://nodejs.org/en/docs/guides/nodejs-docker-webapp/
The docker container is up:
> CONTAINER ID IMAGE COMMAND CREATED
> STATUS PORTS NAMES 32b2e34bf21f
> my-server "docker-entrypoint.s…" About an hour ago Up
> About an hour 0.0.0.0:3000->3000/tcp distracted_blackburn
and is accessible within the server (checked using curl -i localhost:3000 and curl -i 0.0.0.0:3000)

More information:
netstat -tulpn has this row related to the port.
tcp6 0 0 :::3000 :::* LISTEN -
I added ufw rules so it doesn't seem to be FW problem.
3000 ALLOW Anywhere
3000/tcp ALLOW Anywhere
3000 (v6) ALLOW Anywhere (v6)
3000/tcp (v6) ALLOW Anywhere (v6)
But no matter what I'm doing, I can't access the server from server-ip:3000 in my browser(outside the ubuntu)
Thank you.

This is the log that i can see in my nginx access log, I need this data in my node server.
(004026579154BP05000004026579154111213V0000.0000N00000.0000E000.0000000000.0010000000L0000021C)
1) I am using elastic Beanstalk, i don't know how can i pass the above value to my node server module? If its possible to get that value as http or https request inside my node express module.
2) If i have to run a net server, than in which port should i listen for tcp, and how nginx will know about that port, for http server port, i use process.env.port
I have a node.js application running on openshift. After testing my code on a local environment I pushed it up to my instance on openshift. After doing so, I went to check those changes on the public site and my browser reported that I was getting too many redirects. I tried to look at my haproxy status and even that was getting too many redirects.
I have done some investigation and here is what I've found:
I checked my nodejs logs and my node server started successfully (no errors)
I've ssh'd into my machine and ran curl -vvv $OPENSHIFT_NODEJS_IP:8080 and I was returned my index.html as I should.
When I run curl -vvv http://minutepolitics-minutepolitics.rhcloud.com/ I get this response:
RESPONSE:

Also, when I ssh into my machine and run /etc/init.d/haproxy start the output is: Starting haproxy: [ALERT] 294/230821 (134951) : Starting frontend main: cannot bind socket [FAILED]
From here, I don't know what to do or try to get this working again.
Any and all help will be greatly apprecaited! Thanks!!
We are using the telnet mechanism to send http request to server and get the response.
We noticed a strange thing when using the telnet for sending the HTTP GET request.
The first method is working in most of the environments but it's not working in one of the environment. But The second method(instead of relative path, use the complete path) is working fine in this environment.
**
Method1:
**
(printf "GET /test.jsp HTTP/1.0\nAccept: */*\nUser-Agent: WatchDog\n\n"; sleep 9) | telnet xx.xx.xx.xx 8093
Trying xx.xxx.xx.xx...
Connected to xx.xx.xx.xx.
Escape character is '^]'.
Connection closed by foreign host.
**
Method2:
**
(printf "GET http://xx.xx.xx.xx:8093/test.jsp HTTP/1.0\nAccept: */*\nUser-Agent: WatchDog\n\n"; sleep 9) | telnet xx.xx.xx.xx 8093
Trying xx.xx.xx.xx...

Why the method1 is not running in only one environment? do we need to check some thing in that environment?
Pls give your suggestions...
Thanks,

HTTP/1.0 (RFC 1945) specifies the line ending to be CR LF. Some servers may apply this rule over strictly. Try with sending the request with \r\n as line endings. Sending absolute URIs is also reserved for use by proxies (section 5.1.2 of RFC 1945).
If varying line endings and URI style doesn't help you'll have to look at the servers configuration/implementation, as I can not see anything wrong with method 1.
Apart from the line endings which must be \r\n and your accept header which should be */* instead of /, your first request doesn't have a host name.
An HTTP 1.1 server may deny HTTP requests that do not have a host set, either in the absolute request-URI or in a Host-header.

Did some further digging for you and found the root cause is due to misconfigured routers. You can read about it all here.
The workaround that article mentions is to:
echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale
However, this file has changed and on newer setups you need to instead:
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
You will need to be root when running that though.
