I want to create reverse proxy server for two different server (A) public server which is in one VPN and server (B) which is in another VPN I have tried reverse proxy from this blog given below its not working please help me out

i have the following case: i've had an app hosted on some cloud hoster's server and it's own domain, now i've migrated from cloud to selfhosted and what i want to do is to redirect all users in my local network from the old domain to the new one i.e. when a user tipes previous url into it's browser it opens new urk. The main problem is that i can't influence on the old domain, but can configure my local proxy server apache.
There are 2 ways to achieve that:
The simplest way is to edit the hosts file on your local network computers (on windows you can find it in c:\Windows\System32\Drivers\etc\hosts (or /etc/hosts on Linux) and add the entry for your olddomain internalserverip like "IP_ADDRESS DOMAIN_NAME www.DOMAIN_NAME".
You will need to create a bind server on your local network to answers the local queries and configure the zone for your old domain like you would when the domain was hosted on cloud, you just need to put your internal server IP in the A entries.
In both situations if your web server is configured with only the new vhost entry , you will need to configure it with the old vhost (if there is no vhost configure you will not need to do anything)
I have read many similar questions and found numerous articles elsewhere but I'm still unsure how to solve this.
What I'm trying to achieve:
Set my node app on AWS EC2 up to be able to communicate on HTTPS for free or at the lowest cost possible, while still being production ready.
What I have done:
Added inbound rules on my EC2 instance to accepts all traffic
on HTTP and HTTPS and additionally added a rule for HTTPS on PORT 443
specifically.
Set my node app to listen on port 443.
Most articles I have read recommend setting up a reverse proxy server using NGINX and a custom domain with an SSL certificate.
This leads me to the following questions:
Do I need a custom domain for my backend, for it to communicate on HTTPS?
If yes, can I use my Firebase free domain or a subdomain of it? E.g. https://myapp.firebaseapp.com/ or https://api.myapp.firebaseapp.com/
If yes and no, and I buy a custom domain, can I use mydomain.com for my frontend and api.mydomain.com for my backend - can this be done using the same SSL certificate?
Do I need a reverse proxy server?
We have a SharePoint site https://example.com hosted on port 443.
There is another site https://anotherexample.com that should be hosted on same server and without port (i.e. 443).
Both the certificates are issued to different host names (i.e. not wildcard certificate).
How can I achieve above scenario?
Any help is much appreciated!
Edit: I'm working on IIS 8.
Best way to achieve this on IIS 8 is to use Server Name Indication. It allows the server to host multiple certificates for multiple sites under a single IP address.

I have two IIS servers sitting behind a load balancer. And my application's DNS is app.domain.com. I should have a way to communicate from one server to other server without touching load balancer. Application in both servers is listening to port 80. Also I have more than one application deployed in same port in these servers. How can I refer to (URL) to individual servers without using DNS.
Use IP:port with HOST header to distinguish between multiple applications in each node.
I'm trying to learn about why reverse proxy servers are useful. I just read...
Security and anonymity – By intercepting requests headed for your backend servers, a reverse proxy server protects their identities and acts as an additional defense against security attacks. It also ensures that multiple servers can be accessed from a single record locator or URL regardless of the structure of your local area network.
https://www.nginx.com/resources/glossary/reverse-proxy-server/
Why is it helpful that the identity of your backend servers are hidden? Couldn't one just still attack them through the reverse proxy server like how any normal client visiting the app would access them?
You can fine-tune the access restrictions for every request, apply rate-limiting and load-balancing so a possible attack may not bring down your whole infrastructure. Especially the load-balancing aspect is key. Additionally, the only server visible to the internet is the reverse proxy, so it's not a trivial task to map your entire server structure as it would be if you exposed them all.
A common use-case is setting the reverse proxy up as the SSL gateway so you can communicate via HTTP behind the firewall. Failover for non-responding servers is also possible. Adding additional servers to the setup is trivial this way.
Apart from this, the immediate benefit is a centralized setup that you don't have to replicate for all the servers behind the firewall. Also, a reverse proxy enables you to expose only HTTP/HTTPS port for one external IP address but have multiple services running with local IPs you can route wherever you want.
Please note that this question likely belongs on Server Fault since it's related to network and server infrastructure.
“A reverse proxy can hide the topology and characteristics of your back-end servers by removing the need for direct internet access to them. You can place your reverse proxy in an internet facing DMZ, but hide your web servers inside a non-public subnet.” [ 1 ]
