LND funding transaction stuck in mempool due to low fees I have a funding transaction stuck in mempool due to low fees. Searchng around I have find that there is "BumpFee" wallet option to push your transaction. i have tried in this way:

~$ lncli wallet bumpfee [Channel_point] --sat_per_byte 150

>[lncli] rpc error: code = Unknown desc = the passed output doesn't belong to the wallet

When type:

~ $ lncli pendingchannels

i can see the transaction waiting for confirmation, but when type:

~$ lncli wallet pendingsweeps


  {
                "pending_sweeps": []
    }


there arent.
The transaction is still present when type:

~ $ lncli listchaintxns

Someone can  try to explain or have had similar behaviour?
Don’t found so much useful stuff in Github

I solved the problem whit CPFP (children pay for parent).

I used the  unconfirmed change of the fund TX stuck in mempool to open a new channel.

At the time of broadcasting TX the median fee is around 150sat/vb, so i chose to slight increase at 200 sat to ensure good probability to push the first fund tx and the second one in the next block avaible.
