Website Access Issue from Azure Virtual Machine

Question

Website Access Issue from Azure Virtual Machine

Ujjval Bodiwala 0

We are unable to access the website from an Azure virtual machine using the public IP address PII.

We have verified the traffic from the website side, and it has been confirmed that the website is not receiving any traffic from this public IP address.

Please assist us in identifying the cause of this issue and advise on the next steps to resolve it.

Hi @Thanmayi Godithi ,

We are able to access all other websites without any issues. However, this particular website is not accessible. Therefore, we are checking with the Azure support team to confirm whether the site is being blocked from the Azure network.

Hi @Ujjval Bodiwala,

Thank you for the update.

Since the VM can access other external websites, this confirms that Azure outbound connectivity is working and Azure is not blocking internet access by default. When only one specific website is unreachable, the issue is usually on the destination side, such as IP allow-listing, geo-blocking, or reputation-based filtering against Azure public IPs.

Next steps:

From the VM, run:

curl ifconfig.me

Share the outbound public IP with the website owner and ask them to verify whether it is blocked.

Run:

curl -v https://<target-website>

to check if the failure occurs at the network or TLS/application level.

If outbound traffic passes through Azure Firewall/NVA/proxy, confirm no domain-specific rules are blocking it.

If the destination confirms blocking, the fix would be on their side (or by using a dedicated outbound IP such as NAT Gateway or Azure Firewall).

Kindly let us know if the above helps or you need further assistance on this issue.

Hi @Ujjval Bodiwala,Based on the output, your VM’s outbound connectivity is working correctly for other sites, and the connection to 1800thesign.com is timing out, which indicates that the destination server is not accepting traffic from your VM’s public IP.

This is not an Azure networking issue, as NSGs, routing, and general outbound connectivity appear to be functioning correctly. The next step would be to contact the website owner or support team and provide them your VM’s public IP so they can confirm whether it is blocked or needs to be allow-listed.

Hi @Ujjval Bodiwala,

Thank you for sharing the details on Microsoft Q&A.

Since the website is not receiving any traffic from the Azure virtual machine, this typically indicates that outbound connectivity from the VM is being blocked or redirected within Azure before it reaches the destination. To help identify the exact cause, could you please validate and share the following details:

1.VM status

Is the virtual machine showing Healthy / Running status in the Azure portal?

2.Network Security Groups (NSGs)

Are there NSGs applied at the NIC or subnet level?
Do the outbound NSG rules explicitly allow Internet traffic on ports 80 / 443?
Any custom deny outbound rules present?

3.User Defined Routes (UDRs)

Is there a route table associated with the VM subnet?
Is there a 0.0.0.0/0 route configured, and what is the next hop (Internet / Virtual appliance / Azure Firewall)?

4.Firewall / NVA path

Is the VM’s outbound traffic routed through Azure Firewall or a third‑party NVA (e.g., FortiGate, Palo Alto, proxy appliance)?
If yes, please confirm the firewall rules allow outbound traffic and SNAT is enabled.

5.IP Flow Verify (Network Watcher)

Run IP Flow Verify for the VM to check whether outbound traffic on port 443 is Allowed or Denied. This helps determine whether NSG or UDR rules are blocking the traffic.

6.VM‑level test

From inside the VM, please share the output of the below via "Private message":
1. curl -v https://<target‑website>
2. curl ifconfig.me (to confirm the outbound public IP used)

You can refer to this official troubleshooting guide for validation steps: https://learn.microsoft.com/en-us/azure/virtual-network/troubleshoot-vm-connectivity

Sharing the above information will help narrow down whether the issue is related to NSG rules, routing (UDR), firewall/NVA configuration, or outbound SNAT behavior, and advise the next steps accordingly.

Kindly let us know if the above helps or you need further assistance on this issue.
