I have built a docker container with docusaurus server and opened port, but the website is not accessible and throws an error like this. How do I allow all the ip address in the docusaurus server?
yarn run v1.22.19

$ docusaurus-start
LiveReload server started on port 35729

This problem often happens due to slow internet connection. Please check your Internet connection.
I have already added the HTTP TCP Port 80 to the inbound rules, but I still get the error:

You probably have to run your node.js script with sudo as you want to listen on port 80.
You cannot run a process that listens on low ports (below 1024) without root privileges.
You either try to run as sudo, as stated above, or start to use a reverse proxy (nginx for instance), start the process on another port and use the reverse proxy to forward the calls from port 80 to whatever port you started the process on.
The error code EACCES means you don't have proper permissions to run applications on that port. On Linux systems, any port below 1024 requires root access.
you need to use reverse proxy to forward the calls from port 80 to 8080 for example.
I can't understand one thing- does NodeJS allow to listen to custom hostname? Not localhost. Because when I listen to my website url (example.com), I'm getting the following error:
Error: listen EADDRNOTAVAIL example.com ip-address:1000 at

Why does it happend? And can I listen for POST messages from external site URL?
Why does it happend?
This happens because the hostname and port you requested isn't available to you.
can I listen for POST messages from external site URL?
No, You can't. server.listen() accepts hostname and port
Begin accepting connections on the specified port and hostname. If the hostname is omitted, the server will accept connections on any IPv6 address (::) when IPv6 is available, or any IPv4 address (0.0.0.0) otherwise. Omit the port argument, or use a port value of 0, to have the operating system assign a random port, which can be retrieved by using server.address().port after the 'listening' event has been emitted.
And further digging into list of Node.js Common System Errors docs and exhaustive list, It is clear that, Address not available was the case.
EADDRNOTAVAIL Address not available (POSIX.1).
I am writing an Node.js application on Express.js. I have a Redis server installed on an EC2 instance running on UBUNTU Server 16.04. I have installed npm modules for Redis.I have mentioned the port and the host like this:-
var redis = require('redis');
var client = redis.createClient(6379,"127.0.0.1");
When I try connecting to EC2 instance of Redis, I get an error like this:-
events.js:141
throw er; // Unhandled 'error' event
^
Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
at Object.exports._errnoException (util.js:870:11)
at exports._exceptionWithHostPort (util.js:893:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1061:14)
How do I connect to redis which is running on ec2?
from the error message, it seems like redis isn't actually running on your host. i would check that redis is indeed running like this:
ps auxwg | grep redis
and check for a running redis process. another, simpler way would be to use the 'telnet' command to attempt to connect your local redis instance like:
wintermute:~ 07:52:58 melgart$ telnet 127.0.0.1 6379
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
in my case, redis is up and running so i get the 'connected' response. HTH
