If your autoscale pool isn’t scaling, or you’re receiving an Autoscale Pool Error with a message like “Invalid resource: failure creating Droplet”, it may be caused by one of the following issues:
The VPC network for the Droplets in the pool has no more unallocated IP addresses. You can view the number of addresses available in a VPC network on its details page in the control panel.
If the VPC is out of IP addresses, you can create a new VPC network with a larger IP range, then update the autoscale pool’s Droplet configuration to use the new network.
The Droplet configuration is no longer valid. For example, this may happen if the Droplet plan or image is no longer available in the selected region or if the SSH keys for the Droplet are no longer available on the team. Try creating an identical Droplet outside of the pool to verify that the configuration works.
You’ve reached the Droplet limit for your team. You can view your team’s Droplet limit and request an increase on the team’s Settings page under Droplet Limit.
The selected datacenter has no more capacity. Check our regional availability page and status page for more information about datacenter availability.
