Client application and Signoz on different Windows server - open-telemetry

When Signoz is running locally via Docker with the client application in the same server, everything is working. However, if I configure the same application on another Windows server, I got connection timed out exception. There's no firewall issue as if I host another dummy application on port 4317, the other server can access the resource.
Please help

Connection has timed out when trying to access spring boot app from another machine

I'm trying to deploy a spring boot app which will be usable in a LAN. I'm running the command mvn spring-boot:run, the application is launched perfectly, i can access it via localhost but not via other machines : The page loads until the error : The connection has timed out appears .
ANy recommendations ?
It is not accessible because the port in which your application is running is not exposed to the other machines. You can open firewall port to access it across the network.
The best approach is to setup either Apache httpd or nginx as fron't server to server your application on regular ports(80 and 443).

How to solve google chrome "Failed to load resource: net::ERR_CONNECTION_REFUSED" issue in windows 10 when server is running on Ubuntu 18.04?

I am trying to run this project on Ubuntu 18.04 server. I am running both server and client on this machine. Then from windows 10 with port 9000 I am getting access to client in my chrome browser at http://localhost:8000/#/
The browser loads the project but the problem is I can't log into the website with trusted account and some other data do not get loaded . When I see browser console I see an error message saying:
Failed to load resource: net::ERR_CONNECTION_REFUSED
This is the server setting:
This is the client setting and putty setting to connect to client.
VPN has been used to connect to server via PuTTY.
The error message in browser:
Could anyone shed some light on this issue? Is it related to windows 10 or VPN or some other issues? I followed some steps from here https://www.ionos.com/digitalguide/hosting/technical-matters/err-connection-reset/
By default, the Flask development environment uses 127.0.0.1 (localhost), which restricts access to processes on the same host (except for VMs/containers, which aren't a factor here).
To access Flask from outside of localhost (e.g., from your Windows 10 machine), use the IP address 0.0.0.0. (You can pass it to run(), or via a command line option of the flask command.
However, do note the warnings about (not) using the development environment for production use.

Getting Tomcat 7 to work on remote CentOS 7.5

I am trying to run a website (WAR-file)on a remote CentOS 7.5 VM.
I have access to this VM through ssh connection with putty and am able to remote view desktop. The current problem is that even though Tomcat can start, when trying to wget or via browser to view the website a "Connection refused" is returned. I have checked that I request from the right ports and Tomcat does not throw an exception on startup that no port could be opened.
Has it something to do with firewall, which might be preventing access to the port.
Or you might want to map the exposed tomcat port to an external port.

Unable to connect to WCF server port

I created a WCF service and deployed it to my production environment (Windows 2008). The client (also Windows 2008) cannot connect to the server port. I have stopped the Windows Firewall service on the server, and I can see the port listening when I use netstat from command line on the server. I am fairly sure that it is a problem related to the port because I can ping the server, but when I tried to do telnet serverIP port, I got an error. The client machine can connect to other machines on the network (e.g. DB server) so it does not seem to be a problem on the client side. Any ideas on what else could cause the port to be blocked?
Thanks
