How to open access to the local server on apache tomcat (java) from the outside?

Question

Java

The bottom line is that today you need to hand over the project, the java back-end is launched on my local (apache tomcat via idea) server and is accessible from the browser as follows localhost: 8090.
Actually, it’s worth saying that the whole thing is on a laptop and the connection is made through a router (and only this way, because otherwise, I can’t even do it for a while) TPLINK MR3420 router (actually mine).
What I tried to do:
1) opened port 8090 on the router
2) Set my PC on the network with a permanent address (192.168.0.23) (if I understood correctly to my poppy address for my router) 3) Added
a virtual server

domain name foodstories.hopto.org and installed the corresponding utility (DUC) on my computer.
And configured:

Actually, when going to foodstories.hopto.org:8090/login, nothing worked. Please help me figure out how to set up access to the local server from the outside and set it up.

Answer 1

Dynamic DNS only promises to resolve your domain address to your ip. But! If your provider, in turn, has not opened the port (s) to your machine, nothing will come of it. The ip of the provider will be allowed.
Dynamic DNS is useful if you get a white (available on all ports outside) but dynamic ip when you connect to the Internet, and is useless if you are behind a NAT provider (the so-called gray ip).

Answer 2

What does "open a port on the router" mean?
Where did you open it?
You need to map some port from the outside to your laptop + port.
Look on the router for port forwarding, it may be in the NAT setting and map that, for example, port 80 is mapped to your 192.168.0.23:8090

Answer 3

Is there a direct ip? Request http://Your-ip:8090 what does it issue?
