Do nodebb support latest version of nodejs version v12.14.0 ?

1. I am not able to remove 4567 from http://subdomain:4567
   How to do it ?
   Steps I am following
   (a) Reading from here https://docs.nodebb.org/configuring/proxies/apache/
   (b) Making subdomain.conf , keeping it inside /etc/apache2/conf.d/includes
   and attaching this line Include /etc/apache2/conf.d/includes/subdomain.conf into httpd.conf
   (c) Changing URL of config.json inside NodeBB folder to http://subdomain.conf

Code which I am using in subdomain.conf is as follows :
<VirtualHost *:80>
ServerName www.sub-domain.com
RequestHeader set X-Forwarded-Proto "http"

ProxyRequests off
<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
RewriteCond %{QUERY_STRING} transport=websocket    [NC]
RewriteRule /(.*)           ws://127.0.0.1:4567/$1 [P,L]

ProxyPass / http://127.0.0.1:4567/
ProxyPassReverse / http://127.0.0.1:4567/

</VirtualHost>

@PitaJ
Do i need to do mongorestore before installing nodebb or can we do it after installing nodebb also ?

@PitaJ
Yes sorry , you are right,
mistyped it by mistake

Now the status is my new nodebb with latest version is running without my data
How can i use mongorestore , so i can populate my new nodebb version with backup data ( most important )

Please guide me

@PitaJ
Thanks a lot
Now everything is working fine

Previously I was running nodebb version v.10.1 for last 1 year but when I try upgrading it to latest version
(before which i did mongodump first which results in making dump folder with two subfolders named admin and nodebb),

it kept me asking to install sharp first, which cannot be installed on centos 6 . So I changed my server to centos 7 .

Now the status is my new nodebb with latest version is running without my data
How can i use mongodump , so i can populate my new nodebb version with backup data ( most important )

Please guide me

@PitaJ

I did a fresh install of nodebb using nodebb documentation available at https://docs.nodebb.org/installing/os/centos/

Along the process after running ./nodebb setup

1. I was asked to make administrator username , email and password .
2. Mongo database and password
   So i fill all the details after which i run ./nodebb start

Then i see nodebb page .
When i click login and enter my administrator details
it reroute to same login page and admin portal is not getting opened

Following are the results :
1.After browsing http:/subdomain.com:4567

2.After doing admin login

3.Now clicking admin

4.After clicking admin , why it is rerouting to login page and why it's not opening admin dashboard

@PitaJ
I have already paid for the following services :
1. Os : centos 7
2. Apache2 (EasyApache4 software in hostgator)

@PitaJ

I am able to open nodebb on : http://sample.sub-domain.com:4567
but not https://sample.sub-domain.com

@PitaJ
I have written this code in separate subdomain.conf
location where i saved this file : /etc/apache2/conf.d/includes

<VirtualHost *:80>
    ServerName www.sub-domain.com 
    ServerAlias sub-domain.com

    </IfModule>
</VirtualHost>

        </IfModule>
    </FilesMatch>

    ProxyRequests off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    # Custom Error Document when NodeBB is offline
    ProxyPass /error-documents !
    ErrorDocument 503 /error-documents/503.html
    Alias /error-documents /path/to/nodebb/public

    # Websocket passthrough
    RewriteEngine On
    RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
    RewriteCond %{QUERY_STRING} transport=websocket    [NC]
    RewriteRule /(.*)           ws://localhost:4567/$1 [P,L]

    ProxyPass / http://localhost:4567/
    ProxyPassReverse / http://localhost:4567/

    # Log stuff
    #ErrorLog ${APACHE_LOG_DIR}/www-example-error.log
    #CustomLog ${APACHE_LOG_DIR}/www-example-access.log combined
</VirtualHost>

But still I am not able to do it
what mistake i am doing ?

@PitaJ
When I am doing curl http://localhost:4567/ on putty
I am getting nodebb html page

but when i am running nodebb through my subdomain , I am getting a list of directories of nodebb .

For doing configuration of reverse proxy : I have followed this link
https://docs.nodebb.org/configuring/proxies/apache/

Any advice , stuck from last 24 hours .
Not able to find solution
