I have retired my pool during epoch 273. After 274 was completed, my pool showed as retired and my stake address now has 500 ADA. I am using the CoinCashew Guide 18.11 Claim Your Rewards Guide: How to build a Cardano Stake Pool - CoinCashew
Everything goes very smoothly until I try to submit the transaction and get the following error message.
cardano-cli transaction submit --tx-file tx.signed --mainnet
Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraMary (ApplyTxError [UtxowFailure (MissingVKeyWitnessesUTXOW (WitHashes (fromList [KeyHash “273332da8d83602697d3e192be4193dcf2575f6d80307684506a9bab”])))])
Where did I mess up? And how do I fix it?
