We've had an environment running for ~2 years but since a few days ago suddenly we can no longer launch VMs that are attached to the Load Balancer. We have not made changes to the environment.

If we set up a new VM from an image and configure it to be in the Network Load Balancer Backend Pool, the VM will fail to start with a NetworkingInternalOperationError

We tried redeploy, reapply, restart, etc. without any success.

When we set up a new VM without connecting it to the Load Balancer, it can start, and is healthy. And if we later manually connect it to the LB, all is fine.
