How can I reach my VM in Azure ML studio via external port 8000?

Christopher 5

I can ping the public IP, but if I try any port I get no response back. The local IP works with my api hosted on the machine but it is unreachable via public IP. I have been to the networking tab and everything is enabled. What else can I check?

Hello Christopher,

If you already have the AzureML enable outbound unrestricted like the image

Here some additional verification steps:

NSG Associated to the vnet and also if there is NSG associated to the network interface

If you’re using a network security group (NSG) or a firewall, create an inbound rule to permit traffic on port 8000.

Verify that the port is indeed listening, you can use the netstat -ant command on your VM.

Let me know if this help you to solve the issue.

netsta -ant is listening and gives me this line as well:
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN

I have nothing set in NSG and all outbound is enabled

Can you try from another Vm on the same vnet to the private and public IP that is exposing the 8000. Port? Is it working?

Verify the OS firewall (For windows wf.msc / for linux Ip tables)

Ok so I fired up another vm on the same network and it did not work. I tried on another source machine and even changed networks and still nothing gets in. I am really confused at this point. I am using linux

telnet 10.0.0.4 8000

Trying 10.0.0.4...

Connected to 10.0.0.4.

Escape character is '^]'.

using the local IP worked

sudo netstat -plnt | grep ':8000'

tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 7555/python

it is listening... really stumped here

If you cannot reach from another vm on your same vnet. You need to check your local firewall. Depends on your linux distribution you can poweroff the firewall or disable the iptables (Only for testing purposee.) Let me know if you need more help here.
