IIS Apache and Node.JS HTTP all on the same server - node.js

I have one windows server already running sharepoint on 80/443 and the site works correctly.
We're trying to add more functionality by installing NodeJS and Apache
I've set apache to listen on 8080 and the default website comes up.
Node is running on 3000 and I can access the explorer that way as well.
My questions come from this. The server has a complete certificate chain installed on it and https://:8080 comes up correctly, but I can't get the node stuff to work on https: Secondly it appears while I have proxy pass set up correctly within my httpd.conf, either something is wrong within that as if I goto the https://:8080 /api/and anything beyond that, I get 503 errors and the page can't be displayed.
I'm unsure what I'm doing incorrectly here as from reading the documentation on proxy module, it seems that everything is setup and configured correctly.
Netstat shows listening on 3000 and 8080 and 80/443 for my SharePoint farm.

I had to configure the ssl settings for the proxypass to use the IP address of the local machine. After doing that I was able to connect correctly.
This allowed for connecting on :3000 via telnet to the localmachine and allowed for explorer to be viewed with https://:8080 the correct way enforcing our certificates.

Can connect to nginx server inside LAN but not publicly

I'm trying to set up a Mastodon instance on my Raspberry Pi 4 at home, running Raspbian/Debian Linux. I have no idea what I'm doing.
The nginx server is running, working. When I access it from localhost or from inside the LAN, it gives a result like this, as expected:
When I try to access it from outside the LAN, it eventually times out or gives a "connection was reset" error.
Or in firefox:
At first I suspected that it was a problem with my firewall, like maybe it was blocking HTTP traffic into it. But it's allowing HTTP traffic through. I even stopped the firewall entirely, but it's still doing the same thing. (I'm using IPTables)
All of the necessary ports should be forwarded to the pi on my optimum router:
Here's the site's nginx config, just an edited copy of mastodon's given nginx configuration template. I have the HTTPS server commented out, as I'm only working with HTTP right now. I'm trying to get the http server working so I can use certbot to get an SSL certificate, but certbot's unable to connect to the nginx server, runs into the same "connection reset" error. The server_name is irrelevant (or is it?) as i'm just trying to connect to it through IP right now, and commented out the other "location" properties that the template came with, as I'm just trying to get the server to work in the first place, running mastodon on it and getting the SSL certificate and getting the domain to work will come after.
What causes it to work inside LAN but not outside it? Even with the necessary ports forwarded to the pi?
Edit:
Here's what it looks like inside the LAN, working correctly:
and here's when I try to access it outside the LAN (through ProtonVPN in this case)
https://www.reddit.com/r/OPTIMUM/comments/rxjw1v/optimum_internet_not_forwarding_traffic_on_port_80/
By default, Optimum blocks ports 80 and 25, even if they are port-forwarded.
Optimum support referred me to this obscure page that I couldn't find linked anywhere on the site, did exactly what i needed: https://www.optimum.net/internet/boost/

TCP server won't work on Openshift NodeJS

I've used the openshift-cartridge-tcp-endpoint cartridge to try and make a TCP server which I can access from a desktop application.
I've set it up on a scaleable application and I can see the OPENSHIFT_NODEJS_PORT_TCP and OPENSHIFT_NODEJS_PROXY_PORT_TCP values when I list the environment variables using 'export' when ssh'd into my application.
The problem is, when I do 'rhc ssh APP_NAME oo-gear-registry all', no port is listed over which I can access my TCP application and when I try to access the application over the port given by the HTTP server, it does not connect. Do I have to take additional steps to make the port show up and be accessible?
It looks like that cartridge is over 2 years old, and probably doesn't work with the current version of OpenShift Online, as it only exposes port 8080 publicly and uses an HTTP/WS reverse proxy, so only http or web services connections would work. You might try logging an issue with the cartridge's creator here (https://github.com/Filirom1/openshift-cartridge-tcp-endpoint/issues) and ask them if it still works or not.

WebSocket over SSL: Cloudflare

I have a website behind cloudflare. I need to enable websockets over SSL without turning off cloudflare support. I have a PRO plan and hence won't get the new websocket support. I am using Nginx to proxy a SSL connection to a web socket running on a node server. Now, I read somewhere that cloudflare could work with approved ports would support websockets. Hence, I'm using 8443 for the Nginx port and another port for the node server. Using wscat it returns a 200 error.
$ wscat -c wss://xyz.com:8443
error: Error: unexpected server response (200)
I know that the websocket is expecting a 101 code. However, if I visit https://xyz.com:8443, I can see the page displayed by the node server telling me proxy is working. Also, once I turn off cloudflare support, the websocket starts working. Any clues to get this working. I know I can create a subdomain but I'd prefer running the websocket behind cloudflare.
If you're trying to access this through CloudFlare's network you'd need to explicitly have web sockets enabled on your domain before they will work -- regardless of the port. As in, even if the port can pass through our network, that won't automatically mean that web sockets will be enabled or accessible on your domain.
You can try contacting our support team to request an exception to see if they can enable it for your domain, but typically this is still only available at the business and enterprise levels.
Disclaimer: I work at CloudFlare.

Solr with Jetty on LAMP server - Admin page access issue

I have Solr with its default Jetty that came with example directory installed on Linux server which has apache2 as its web server.
Now, within the same private LAN, when I open a browser and type in http://<ip-address>:8983/solr works ONLY when I do port forwarding otherwise it doesn't work. I am not sure what could be the problem? Please note this installation has been done on a remote server in a hosting environment for production deployment and I am a beginner wrt deployment stuff.
You can use the jetty.host parameter during startup to allow direct access to Jetty.
The -D option of the java command can be used with the followin syntax:
java -Djetty.host=0.0.0.0 -jar start.jar
In this way Jetty can be reached from all the hosts.
However this is not the ideal setup IMHO. I prefere to setup Jetty to listen only on localhost, implementing the client with another frontend server which listen on port 80. If you want to implement the frontend on another server you can use iptables to limit the incoming connection, dropping everything on the 8983 port if the IP is different from the one of your frontend server.
This image depicts my preferred setup for a LAMP stack includin SOLR:

Error while starting web application

When you right-click a Web site in the Microsoft Internet Information Services (IIS) Microsoft Management Console (MMC) snap-in, and then you click Start, the Web site does not start and you receive the following error message:
The process cannot access the file because it is being used by another process.
What have to do.
To resolve this issue i got this solution:
You must use the Netstat.exe utility at the command line to see if another process is using port 80 or port 443.
But how to ensure that is these Ip are in use or not ? in terms of status ? What should its status ?
Second solution is : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList.
But this key is not found .
Lalit, this should probably be on ServerFault.com as this is more of a server administration question. With that said, you probably have more than one website listening on port 80 or 443 without the use of host headers. When using port 80, you cannot have more than one site on the port without specifying the domain name(s) to use in your website bindings. 443 (HTTPS) gets a little more tricky as you typically cannot have more than one site use 443 even if you are using host headers (there are exceptions like wildcard SSL certs). This is due to IIS not being able to read the host headers and know which SSL cert to use to decrypt them since they are encrypted.

Finally i keep error as it is and I reinstall IIS and required software.
