Hi, please check below points

Network Security Group (NSG) Rules: Verify the Network Security Group (NSG) associated with your Azure VM. Ensure that there are no rules blocking incoming traffic on the port (4200 in this case) you're trying to use. You may need to add an inbound rule to allow traffic on that port.

Firewall Configuration: Check the firewall settings on your Azure VM to ensure that it allows incoming connections on port 4200. If there's a firewall running on the VM (e.g., iptables on Linux), configure it to allow traffic on the desired port.

Nothing Changing cause i don't think the issue is with the port

this is the error im getting

Error: listen EADDRNOTAVAIL: address not available IP:4200

at Server.setupListenHandle [as _listen2] (node:net:1800:21) at listenInCluster (node:net:1865:12) at doListen (node:net:2014:7) at process.processTicksAndRejections (node:internal/process/task_queues:83:21) {

code: 'EADDRNOTAVAIL',

errno: -99,

syscall: 'listen',

@NDARUHUYE Yves ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

Looks like the error is from your application rather from Azure's platform.

From where are you trying to connect? I assume it's a local computer but correct me if I am wrong.

From the local server, please open Powershell as admin and run
tnc <YOURVMPUBLICIP> =p 4200

And share the results please.

Cheers,

Kapil

Hi,

You cannot use the VM's public IP in your ng serve because it [the Public IP] isn't known inside of the VM. This is normal and expected. Instead, you can use 0.0.0.0, similar to below:

ng serve --host 0.0.0.0

Additionally, in order for your app to be reachable via public Internet you need to A) make sure incoming port 4200 is allowed in the VM's firewall and B) make sure you've allowed port 4200 incoming in your NSG (it appears you have already done this)

Thanks.
