From my Virtual Desktop, I can not access my website

Question

Hello team,

I was wondering if someone here went already through the issue in which we can not access a website from within the virtual desktop provided by Microsoft.

Outside of the VD, everything works fine, but from inside the virtual desktop, it doesn't work. There is no firewall block.

I always got the below error:

"Hmmm… can't reach this page"

Hello Novastratics:

Please follow up the next steps:

1. In the Azure portal, navigate to the Virtual Machine resource that is experiencing the outbound internet connectivity issue. The resource will default to the Overview blade in the left pane.
2. Scroll to the bottom of the Overview blade, and select Connection Troubleshoot under the Support + Troubleshooting header.
3. Select Outbound Connections, and then specify the following options:

• Connection Destination: Other IP address/CIDR
• IP address/CIDR: the internet protocol (IP) address that you are trying to connect to (or enter 8.8.8.8 for a general internet connectivity check)
• Service: HTTPS
• Port: Leave set as 443
• Protocol: Leave set as TCP

1. Select Test connection.
2. If the connection fails, the test results will indicate which NSG or UDR is interfering with connectivity.
3. If the connection is successful, this means that the Azure platform is allowing outbound internet connectivity. Check within the VM for configuration issues in the destination configuration.

You should also head over to your NSG (Network Security Group) and vNET to see if any outbound ports are being blocked for that specific resource. It is quite possible that a port may be blocked OR your Virtual Desktop is having DNS issues.
