Many node-provider actions — onboarding a machine, retiring one,
updating an IPv4 address, changing a principal — are submitted as
proposals to the Network Nervous System (NNS). This page collects the
common reasons those proposals fail and what to check before
resubmitting.

## Before you resubmit

A proposal that did not adopt is not always a bug — it may simply
have been rejected. Distinguish three cases:

1. **The proposal failed to validate** — the proposal payload was
   malformed and the NNS rejected it without a vote. Re-prepare and
   resubmit.
2. **The proposal was voted down** — neurons rejected the substance
   of the proposal. Talk to the community before resubmitting.
3. **The proposal was adopted but the action did not take effect** —
   rare; treat this as an incident and surface it on the Node
   Provider Matrix channel with the proposal ID.

## Common validation failures

Proposals that fail at validation usually do so for one of these
reasons:

- **Wrong neuron ID or principal.** Double-check that the controller
  signing the proposal is the same principal the NNS expects for
  your node-provider record.
- **Stale registry data.** The state the proposal references — node
  ID, data-center key, IPv4 / IPv6 entry — has already changed.
  Re-pull the current registry state and rebuild the proposal.
- **Mistyped fields.** Hex node IDs, IPv6 addresses, and domain
  names are exact matches. A single character off and validation
  fails.
- **Missing reward configuration.** Reward-related proposals require
  the data-center and reward-rate records to exist already.

For each, fix the underlying input, regenerate the proposal payload,
and resubmit.

## Common reasons proposals get voted down

If your proposal validated but did not adopt:

- **Missing forum context.** New regions, new data centers, and
  reward-rate changes need a forum discussion ahead of the proposal.
  Without that thread, neurons typically vote no.
- **Decentralization concerns.** Proposals that would concentrate
  the network in a single jurisdiction, provider, or hardware
  supplier are routinely rejected.
- **Insufficient time on the floor.** Some proposals need a week or
  more for community review before the votes accumulate. Check the
  voting window before assuming failure.

## Where to verify state

- **Proposal status:** look up the proposal ID on
  [dashboard.internetcomputer.org](https://dashboard.internetcomputer.org/).
- **Registry state:** the dashboard exposes node, data-center, and
  node-provider records.
- **Forum context:** searches at
  [forum.dfinity.org](https://forum.dfinity.org/) typically surface
  the discussion thread for any non-trivial governance change.

## When to ask for help

Surface the issue in the Node Provider Matrix channel if:

- Validation keeps failing for a reason you cannot identify.
- A proposal adopted but the on-chain state does not reflect it.
- You are unsure whether a forum thread is needed before resubmitting.

Always quote the proposal ID and the exact error text.
