SubnetLimitReached
A chain-side capacity limit was hit; reduce the size or count of the request
register_network failed because the subnet count is at the network limit and no existing subnet is eligible to be pruned. Check the number of registered subnets (btcli subnets list) against the subnet limit and retry once a subnet becomes prunable.
Declared by the SubtensorModule pallet; it classifies to the semantic code limit_exceeded.
Remediation

The same explanation is available in the terminal: btcli explain SubnetLimitReached.
