I 1-input-1-output legacy transaction will be around 190 vbytes. Adding that to your two previous transactions, and assuming you spend the 19,693 sats you can spend from that address on a fee, your total will be 1047 vbytes paying 25,617 sats, which will work out to 24.5 sats/vbyte, which is nowhere near the required level.
Thank you for your advice, I did what you said and it finally worked, I did the CPFP "6fed3737ab66630899c3d93462aaacdbd3b03626b86d9f870434c12a639d47d6" with 103sat / vbyte this allowed me to have an effective rate of 24.4sat/vbyte and that at allowed to confirme all my other stuck transactions. The method works thank you
