Can you share the txid of the tx you are trying to cancel?

Thx. So the tx does not have a 2fa fee output.

In the bottom right of the main window, click the shield icon ("TrustedCoin"). In the bottom of the dialog that opens, it should say "Your wallet has {} prepaid transactions.". What does it say, how many "prepaid transactions" are there?

Ok, so the wallet has run out of prepaid txs after broadcasting the original tx. Now that you are trying to cancel it, the 2fa server is treating the replacement tx as a new one, and seeing the wallet has 0 prepaid txs, the server is expecting a 2fa fee output. But the client code treats the double-spend-cancel as a special case and does not add the 2fa fee output. Looks like a bug.

As a workaround, if you create a new tx, that would have the 2fa fee output added, paying for 20 more "prepaid transaction", after which the original tx you are trying to cancel could be cancelled.

As another workaround, you could restore from seed words, disable 2fa, and cancel the tx without the cooperation of the server.

Creating a new tx did not help. The second point with disabling trustedcoin solved the problem, transaction double spend. all good thanks
