I need to connect to my Azure VM through ports 3200, 3299, 3300, so I added an inbound ACL rule. It was working at the beggining but after some time it wasn't any more. I guess some seccurity mechanism from Azure blocked my ports. what am I missing?

    Hi @raul menchi,

    Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

    We understand from your query that you are experiencing an issue while trying to connect to the VM. Below, I have shared troubleshooting steps that I believe will help resolve the issue you reported.

    • If you have Azure Firewall enabled, it might be blocking your ports. Check the Azure Firewall rules and configure them to allow traffic on the required ports.
    • Check if there are any NSGs associated with your VM or subnet that might be blocking your ports. Verify that the NSG rules are configured correctly to allow traffic on ports 3200, 3299, and 3300.
    • Review the Azure portal's activity log to see if there are any error messages or warnings related to your ports.
    • If you have JIT access enabled for your VM, it might be blocking your ports. Check the JIT access configuration to see if it's blocking your ports.

    If you have any further queries, do let us know.
