subtoken_disabled

The subnet exists but its token operations are not enabled yet.

A newly registered subnet starts inactive: staking, unstaking, and other alpha operations are rejected until the subnet owner activates it with start_call. there is nothing to fix on your side; wait for the subnet to become active.

Remediation

The subnet is not active yet; wait for start_call

Chain errors

The exact chain error names (from the extrinsic receipt) that classify to subtoken_disabled; the description says what triggered the failure and where to check. Each name has its own page:

Chain error	Description
SubtokenDisabled	The subnet's alpha token is not yet enabled, so staking, swapping, and trading on it are blocked; SubtokenEnabled is false until the owner makes the start_call after registration. Check SubtokenEnabled for the netuid involved.

The same explanation is available in the terminal: btcli explain subtoken_disabled (or btcli explain <ChainErrorName> for one exact chain error).
