I have a nodejs application, I am able to configure https and run it locally on my windows machin, but when I do the same run on my Linux machin it fails with below error.

As suggested by other I tried 'netstat -plnt' but the port 3006 is nowhere used, so nothing to kill.
Not sure if this is code issue or OS issue.
[Update] chnaged the port to 3006
netstat -plnt

First findout your processID for your running process
lsof -i:1234(your port ID)
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
Google 55523 ssurisettii 42u IPv6 0x53ab9cb514809733 0t0 TCP localhost:53991->localhost:us-cli (CLOSE_WAIT)
Google 55523 ssurisettii 45u IPv6 0x53ab9cb51480d473 0t0 TCP localhost:53989->localhost:us-cli (CLOSE_WAIT)
Google 55523 ssurisettii 46u IPv6 0x53ab9cb514809d53 0t0 TCP localhost:53990->localhost:us-cli (CLOSE_WAIT)
this ways shows,
Now you kill the your related processID
suppose your port id contains processID 1234
then **** kill -9 1234 ***
My question is about getting Phusion Passenger and Plesk Onyx 17.5.3 to work together nicely. I have a new server running Ubuntu 16.04.
I am following the official Phusion Passenger tutorial on deploying a Node.js app, and I have followed it successfully to the point where I need to tell Passenger to listen on port 80.
Here are my steps:
With my registrar, I set up a DNS entry for the subdomain pass.domain.com
In the Plesk interface, I define the new subdomain
If I visit http://pass.domain.com in my browser, I get the default Plesk web page.
I follow the "Phusion Passenger: Node.js tutorial" until I reach this command:
sudo passenger start --port 80 --user someusername --environment production --daemonize
Note: I am using a valid custom user name in the place of `someusername'.
I get this error:
Could not start the Nginx engine:
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
It appears that Plesk is already serving the default web page at this address, so Phusion Passenger cannot access it. What files do I need to add or edit to get Plesk to release the address so that Passenger can use it?
EDIT 4: I have found this question which describes similar symptoms. However the OP is using Meteor Up and I am using Passenger. His solution was to get Meteor Up to tell Node.js to run on port 3001, and get nginx to listen on port 80 and proxy requests to port 3001. I had understood that Phusion Passenger already does something similar under the hood.
Is there a way to modify the passenger start command to clarify this?

Note: I have already asked about this issue on the Plesk forum, but it has received no response. I am hoping that asking the Phusion Passenger community here will be more productive. Once I have a working solution, I will post a link from the Plesk forum to the answer here.
Thanks in advance for your insights,
James
EDIT 2: Following #TarunLalwali's advice, I tried stopping nginx, but this produced an unknown error:
$ sudo nginx -s stop
$ sudo passenger start --port 80 --user node --environment production --daemonize
Could not start the Nginx engine:
nginx: [alert] Unable to start the Phusion Passenger watchdog because it encountered the following error during startup: Unable to start the Passenger core: it seems to have crashed during startup for an unknown reason, with exit code 1 (-1: Unknown error)
EDIT 3: Attempting to disable nginx server-wide before invoking Passenger:
$ sudo systemctl disable nginx

You mention that you need the system Nginx (at port 80) to run other subdomains on the server.
Passenger Standalone can coexist peacefully with a system Nginx using two steps:
Run it on a non-conflicting port, for example the default 3000:
sudo passenger start --port 3000 --user someusername --environment production --daemonize
For the domain that you want Passenger to server, tell the system Nginx to proxy to Passenger.
proxy_pass http://localhost:3000;
Remember to reload/restart Nginx to activate the config.
How to do step 2 exactly in Plesk is a question best asked on the Plesk forum, but from the Passenger point of view this setup should work.
I am trying to create a nodejs application that uses SSL. I have the cert, domain, and nodejs configured and working, but I'm having a problem sometimes when I stop my node server using Ctrl+C. I am getting the following error when trying to restart the node server:
Error: listen EADDRINUSE :::443

Now I know this means that the port is in use, but I've tried several things to find the process that is using that port but I cant. A couple thing I've tried that are worth mentioning are netstat:
$ sudo netstat -tulpn

and ps:

but neither of them show me what is using port 443. I have pm2 to keep my node server in a running state, but it keeps saying errored and then I find the EADDRINUSE errors in the pm2 error log. I've been banging my head against the wall for hours. Can anyone assist me? Thanks!
I had this issue and the only command that revealed the process was
sudo lsof -iTCP -sTCP:LISTEN -P
For a few months all has been ok, but now I have a lot of:
mix phoenix.server
[error] Postgrex.Protocol (#PID<0.302.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused
[error] Postgrex.Protocol (#PID<0.303.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused
on localhost.
But:
Postgresql is running
Its config is the same
The config of my phoenix/elixir application is the same too.
systemctl status postgresql shows everything is ok
nothing bad in the log
I can connect to Pg via Pg GUI tool
What's the matter?

Tried to avoid the listen IP only on the '127.0.0.1', so the listen port 8000 is also bind with the '0.0.0.0'. But external http clients still not able to get the http connection setup. Also tried tcpdump, the client SYN can reach to the node server, but not any response from the node.js http server... this caused the issue. Really appreciate your assistance!
