Sometime they can communicates with http.

I'm developing a web server that I had to do from scratch, it works well locally and now I have to implement it on an oracle linux server to be accessed, for example, 123.456.789:3000 on that specific port.
my question is how do i correctly configure the port for that, configure the port in the firewall as follows
firewall-cmd --add-port=3000/tcp --permanent
firewall-cmd --reload
prepare the web server but it is not accessed, I do not know much about this area in particular, the server works like express.js for example
edit: I do not have access to the server configuration console as such
I have a local MAC machine that RDPs into a windows VM. On that windows VM/desktop I have Power BI Desktop installed along with the Cdata PowerBI/Quickbooks ODBC driver (https://www.cdata.com/drivers/quickbooks/download/powerbi/).
On a separate server (which I can RDP into from the virtual machine) I have quickbooks desktop installed (https://www.acecloudhosting.com/) and in single-user mode (opened a company file w/ an admin user). On that server I have also setup QuickBooks Remote Connector (http://remoteconnector.com/), which essentially is used to create an authenticated connection to QuickBooks. This "remote connector" also acts as a lightweight web server that listens for incoming requests (such as a power bi direct query) and uses that to communicate with Quickbooks hosted on a separate server.
However, I keep getting an HTTP protocol error and not sure if it is because the ports are not setup properly or if something in my ODBC connection is incorrect. It is very odd that I can RDP into the remote server from my VM, but when I try to ping the server my request time out despite allowing ICMP responses in the windows file sharing options so I find that odd.
I have worked on this for about 4 hours, but have run out of things to try.

Does nifi use the http server on Linux or does it use it's own? I inherited a nifi server that has some nessus issues related to http. Http service is not running, only nifi. Tring to figure out how to resolve the issues.
NiFi executes within a JVM on a host operating system. The primary
components of NiFi on the JVM are as follows:
Web Server
The purpose of the web server is to host NiFi’s HTTP-based command and control API.

I used to just put my server name and my sql credentials to connect. Now, not connecting. My other domain login can connect to OTHER servers.
When I run the app in Development, it works. Localhost it does not. So, I know the server connection is good. Something with my networking, after I got a new computer.
I've set up nginx in a laptop running ubuntu and I will be using this machine as the server.
But I am programming with Clojure on an OS X laptop and I installed Jetty on OS X. I compiled the .war file on the OS X and run Jetty server on the OS X.
Now I realize that this is probably wrong. Should Jetty be also running on the ubuntu server? Can you explain the correct way to work with this set up?
No, you don't need to have both servers on one machine. Nginx can forward requests to other server by ip
upstream jetty {
server 192.168.1.33:3000;
}
You need to be sure port is opened and accessible (not firewalled) from nginx machine.
> telnet 192.168.1.33 3000
Both nginx and jetty should run on server, on dev running just jetty is fine unless you test "like-production" environment (for example nginx websockets support).
