I can not retire my stakcepool

Hi, I have problem with retire stakepool,

Use this command to create cert

cardano-cli stake-pool deregistration-certificate \
--cold-verification-key-file node.vkey \
--epoch 287 \
--out-file pool.dereg

Then I create ctransaction with fee etc and after

cardano-cli transaction submit --tx-file tx.signed --mainnet

I got this error,

Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraMary (ApplyTxError [LedgerFailure (DelegsFailure (DelplFailure (PoolFailure (StakePoolNotRegisteredOnKeyPOOL (KeyHash "67...8d4433")))))])

Any Ideas, what is wrong?

The node is synced?

Follow the guide (Step 19)

I used this instruction. Node is synced I can send other transaction.

Make sure node.skey/vkey are the correct ones. What’s the pool ticker?

Ticker: BTR

A wild guess - the meta json file hash key is invalid and/or the file has been changed since last update or registration?

Hash seems ok: https://pool.vet/#BTR
