I have an Azure VM that I can't connect to. I have done the following steps. What am I missing here?
Created an endpoint (port 1431) in the portal
Created a rule for port 1431 in the firewall on the VM
Started a server (TCP Test Tool) that is listening on port 1431
Tried to connect locally with a client (port 1431) on the VM - Works as expected.
Tried to connect remotely to the VM - FAILS
If I try to telnet port 3389 (rdp) it works fine.
I have restarted the machine.
Any ideas?
Thanx
Andreas
Make sure the both the public endpoint port and private endpoint port are set to 1431.
In addition, test to make sure you setup your firewall rule correctly. An easy way to do this is to temporarily disable the firewall. Can you connect if you do this? If so your rule is not configured correctly.
Also, what do you mean you "can't connect" being that RDP works?
Lastly, try a different port number and see if it works.

I was able to connect to Azure VM through RDP earlier but now suddenly I'm unable to connect to VM through RDP.
I tried to connect through Powersell.
Even powershell script was able to connect earlier but not working now. Myself didn't changed anything in Azure VM.
I'm getting below errors.
But I'm able to connect to VM through Bastion.
WinRM is already enabled in Azure VM.
I tried by creating new Azure VM and enabled RDP port 3389 but still getting same connection issue.
How to resolve issue.
When debugging RDP issues one tool I use to test connectivity from a windows client is:
start
run
cmd
telnet ip port
e.g telnet 99.99.99.99 3389
noting you may need to install the telnet client from windows features tool
Try this from multiple locations with different public addresses (including from the VM itself in some circumstances but clearly not for your issue).
Does it connect to the RDP Server listening port ?
If the answer is yes then you know the server is listening.
If the answer is no then the port is likely blocked, service is not available or a routing issue could be the cause.
Thinking out loud review the resources you have sitting in front of the VM:
window firewall (Disabling all firewall profiles is a more foolproof way of troubleshooting than setting the RDP-specific firewall rule, see REF)
local network outbound traffic blocks
firewall in front of the vm

I've installed a Windows 2012 R2 VM (free tier) and enabled all ports for external communication (including port 80).
I logged in to my VM and installed nginx webserver (I've also tried to python development server).
I can access the website internally on the VM (using 127.0.0.1 or the internal address of the server 10.1....) but when trying to access it from outside, using the external IP address (which is also the IP address I used in order to login to my server using RDP) I get no response.
Can you please help me understand what I'm doing wrong?
Thanks!
As #evilSnobu points out from his comments, the short answer is to allow the TCP port 80 in the windows firewall on windows VM itself.
Usually, we could login to that Windows VM and run the CMD command netsh advfirewall set allprofiles state off to disable the windows firewall temporarily. Then we can use telnet tool to check if TCP 80 port can be connected.
When we face the same issue no response outside of Azure VM. we can try one or more of the followings:
There is an NSG at the subnet level or NIC level as well which is not allowing data through.
There is a firewall on the VM itself (windows firewall etc.)
There is nothing listening on that port. It should be listening on 0.0.0.0 instead of 127.0.0.1 when you use netstat -ano in the windows CMD.
The service is not staring when you verify the port listening.
Outbound traffic with a specific port is denied from your local machines.
Hope this helps.
I have created inbound and outbound rule on the virtual machine to allow any connection to port 5100 over tcp.
I have created an endpoint in the new Azure portal for TCP and public/private port 5100, but for some reason I can't comprehend I still can't connect.
I tried to turn off the firewall on the virtual machine, but still I can't connect to the virtual machine.
I have previously done this for port 80 with no problems. Does anyone know if Microsoft have changed anything that affects the classic vm's and endpoint configuration?
We can add endpoints via New Azure portal in this way:
We should make sure the update endpoint completed.
Hope this helps:)
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:

I have a problem with my windows azure virtual machine.
I need to open the Port 443 (HTTPS) on the VM.
In the Endpoint Config. of the virtual machine, I opened it and configure the ACL with the following parameters:
Permit
0.0.0.0/0
It's a Windows Server 2012 VM and I created the firewall rule for the public Connection.
A Port Check from ping.eu shows that the port 443 is closed.
The Location of the virtual machine is Western Europe.
I hope, you can help me.
Kind Regards
Sebastian
I also had this issue and it was very annoying! I thought at first I was not setting up the SSL bindings correctly or that it was a certificate issue, then moved on to firewall issues. In the end it was the Azure endpoint at fault.
I had added the 443 endpoint, disabled local firewall and got nothing nothing. I got suspicious when I added a new endpoint on 8080, bound to https and it worked fine.
I deleted the 443 endpoint, shut the Azure VM down from the webinterface after shutting down the client. Created a new 443 endpoint and restarted the VM (I had already tried restarting my win2012r2 vm). It worked.
It must be a glitch in the networking stack of azure endpoints. You are not going mad!!
Hope that helps!

Did you also configure the Endpoint Configuration through the web management portal to forward connections from the ext->int ports ?
Anything you change on the Win2k12 Virtual machine will just affect the VM itself. i.e. opening 443 in the firewall, or configuring routes etc...
But you also need to allow a connection forward from the cloudapp.net public IP address to the internal IP of the box. See the below screenshot.
Another gotcha. In addition to setting up the Endpoint configuration, you need to enable IP Forwarding. This is disabled by default.
IP Forwarding can be found in the IP Configuration settings of the network interface.
