I cannot seem to connect to my website running on Azure VM. I have looked through every single Azure docs.
I allowed incoming connections to port 80 per documentation:
I have a very basic Hello World nodejs app listening on port 80 (i confirmed this app works locally my own system):
I am attempting to connect to the site via the Public IP assigned to me that i see in Azure Portal:
The problem is any attempt to connect to 40.XXX.XXX.230:80 in Chrome simply times out.
I am new to VM's but i think something is wrong with port forwarding?
Another thing to check:
Remote desktop into the virtual machine, and confirm that the virtual machine's local firewall allows incoming HTTP and HTTPS connections.

I am developing a chat app in android using soocket.io. This app needs to communicate with one of the nodejs application listening at port 4000 in my Google cloud Virtual machine through internet.
GCP provided internal and external IP. When I run the internalIP:4000 in browser of VM, I can see it is running fine. But outside of the VM, when I run ExternalIP:4000 it is giving error. I don't know why it is not working.
This is the firewall configurations
So you already established that your service is running fine and is on a correct port (4000).
Now you have to expose to the Internet. By default this port is blocked for any traffic by GCP's Firewall. This way only ports for SSH, RDP or ICMP protocols are open to be able to connect to your VM's. If you need non-standard port you have to create apropriate firewall rule.
You can create it by running using Cloud Shell or running this in your VM's command prompt:
gcloud compute --project=my-project-name firewall-rules create my-app-port \
--direction=INGRESS --priority=1000 --network=default \
--action=ALLOW --rules=tcp:4000 --source-ranges=0.0.0.0/0 \
--target-tags=my-app-server
or create it using Cloud Console. Have a look at the documentation if you have any doubts.
In my example I used my-app-server network tag. You need to add it to your VM that runs the app server - otherwise the rule won't work. It's best to do it this way since you're only exposing one additional port on a single VM which is safest possible solution.
So I'm using an Azure VM that has a public IP address, and I've opened an inbound port, let's say it's 5555.
What I'm trying to do now is to run an application on the VM that has an API via localhost, also with the port 5555. I'm calling it then with public_ip:5555/api/...
Since I was not able to connect to the application from outside, is there something missing here? Most tutorials and resources I've found just mentioned opening the port.
Thanks.
Take a look at Azure's IP Flow Verify utility, which will check your NSG rules to ensure traffic can reach your VM. https://learn.microsoft.com/en-us/azure/network-watcher/network-watcher-ip-flow-verify-overview
If traffic is reaching your VM, check your host firewall and then your application server logs.
I've setup an Ubuntu Server on Azure. On this server, an application is running on port 3000. I want to access this application external. Azure tells me my server has public ip 40.68.XXX.XXX.
When I ping this IP, there is no response, despite ssh works when connecting to this IP-address.
I want to access 40.68.XXX.XXX:3000 external, does somebody know how to get this work?
Yes, you need to open up a port on the Network Security Group (NSG) and open up the port on your firewall (on the VM itself).
Easiest way to open the port is using the portal:
https://learn.microsoft.com/en-us/azure/virtual-machines/virtual-machines-windows-nsg-quickstart-portal
I am trying to open port 8080 in a Windows Azure virtual machine. I have a test website listening in that port, and I am able to access it via localhost, so the website is running.
I have also opened the port in the firewall and created an inbound security rule in azure portal for the virtual machine, but the port doesn't seem to be open to the outside world. I have tried accessing it both via the IP address and the DNS with the same results.
Is there anything else I should be doing?
I am using Azure Virtual Machine (Windows Server 2008 R2 image) provided from the gallery and created Public port and private port using the portal. I did remote log in to VM and I run a TCP server application inside VM (TCP server binds to the private port of the VM). Problem I face is that I can not connect it through the public IP and port (from external machine). I have created a inbound rule in VM's Firewall, where I enable connection to the Private port of VM. I tried recreating the VM, also the new ports. Still problem persists. One more thing I observed is that my TCP Client is able to connect to RemoteDesktop port of the VM also the PowerShell port. But does not connect to the port that I created through the portal. Pls suggest what can be wrong?
Note: I also observed some weird behavior. I enabled all ports for my TCP Server app in Inbound rule of firewall and found that some unknown IP (was similar to azure internal IP) is connecting to my server. Why it is happening?
I would like to understand as to how you are trying to connect with the Virtual Machine, using RDP or trying to test the connectivity, for example, using Port Ping.
Endpoints for RDP and Powershell are configured by default. So if you are trying to connect using Remote Desktop, you can directly connect to the VM using MSTSC from Run and provide the IP of the VM followed by the Port Number using the below format
xx.xx.xx.xx:3389
However if you would like to test the connectivity to the VM, I suggest you to use Port Ping instead of ICMP ping since ICMP traffic is blocked by the Azure load balancer and the ping requests timeout. While Ping.exe uses ICMP, other tools such as PsPing, Nmap, or Telnet allow you to test connectivity to a specific TCP port.
On the other hand, after creating the VM, you can add endpoints additionally as needed. You can also manage incoming traffic to the public port by configuring rules for the Network Access Control List (ACL) of the endpoint.
The private port is used internally by the virtual machine to listen for traffic on that endpoint.
The public port is used by the Azure load balancer to communicate with the virtual machine from
external resources. After you create an endpoint, you can use the network access control list
(ACL) to define rules that help isolate and control the incoming traffic on the public port. For
more information, see About Network Access Control Lists.
