Error when submiting signed tx

[laplasz]

ok so cold key not needed since this is just a stake address registration… seems ok what you did…

ApplyTxError [LedgerFailure (UtxowFailure (MissingVKeyWitnessesUTXOW))]

MissingVKeyWitnessesUTXOW means one or more of the required private keys didn’t sign. The utxo you are querying is payment-source.addr and the build transaction is being funding by with “payment-source.addr” - these are consistent, but the transaction is being singed with payment.skey Do you have a payment-source.skey you can sign the transaction with? This transaction should fail: also, be extra careful to avoid repeating any steps where you may accidentally overwrite existing keys

your are quite at the beginning of the registration… how did you generate the addresses?
