Hello guys, can network security group in azure freeze and stop working. Yesterday my FortiGate firewalls vm was running but I wasn't able to access it via the public IP. I restarted the vm the issue still persisted. We tried to edit the nsg but it didn't let us. We created a new nsg with same rules and attached it to the vm and it now worked and we could access the public IP. What could have gone wrong after 1 month of it working fine.

    anonymous user,

    If you are not able to make changes to the NSG and if you are getting an error, then something is wrong in the backend and that needs deeper investigation as why that happened. As you have already applied the workaround by creating a new NSG and applying it, I suggest you creating a support ticket for finding out what happened on that instance.

    I haven't seen this kind of issue with NSG. It looks like rare case.

    Regards,
