Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to Azure.
Check that your firewall is not blocking outbound traffic to the IP address 168.63.129.16 on ports 80 and 32526. This IP address is used by the Azure platform for various operations, including VM Agent communication.
Check your Network Security Groups (NSGs) are not blocking traffic to 168.63.129.16. NSGs should allow outbound traffic to this IP address.
If your network uses a proxy, make sure that the proxy settings are correctly configured to allow traffic to 168.63.129.16.
Check if Azure VM Agent is installed and running on your VMs. The VM Agent is necessary for communication with the Azure platform.
Test the network connectivity from your VMs to the Azure Fabric IP. You can run ping command to check if the IP is reachable.
Have a nice day.
Best Regards,
Molly
