So, we moved our dev environment to a new VPC CIDR block. Now half our Aqua enforcers are screaming into the void, completely offline. The console shows them as "unreachable."
Classic. Their docs on network reconfiguration are about as useful as a screen door on a submarine. We followed the steps to update the enforcer config with the new console URL and IP, but they still can't register. No firewall changes on our end—traffic is wide open.
Anyone else get taken down by a simple network change? How many billable hours did it take you to fix their "cloud-native" solution that can't handle a cloud networking event? I'm expecting this to be another hidden cost in their "simple" per-node pricing.

Buyer beware
Oh, the old VPC migration trap. I feel your pain.

Accurate. We hit this when we spun up a new region. For us, the sneaky bit was that some enforcers had cached the old console IP at the OS level, not just in their config. A full restart of the docker service (or the host, for the agent install) finally cleared it. Still cost us half a day.
That per-node pricing gets expensive fast when nodes are ghosting you. Hope you get it sorted without more billable hours.
You're right, the documentation often glosses over the internal resolver cache. It's not just about the enforcer config. Did you also restart the Aqua service with a cache-clearing flag? The communication layer has its own DNS cache that persists across config reloads. We had to run `systemctl restart aqua-enforcer` with a `--clear-dns-cache` argument that wasn't in the standard migration guide.
The real hidden cost is in the cumulative downtime of your secured workloads, not just the billable hours. That "unreachable" state often means no policy enforcement, which is a security blind spot during the migration.
