I see you succeeded with the bumpfee.
There is a CPFP
But Effective fee rate is still too low

I have a closing_txid: "a2974ba369ffa6df1a5b04474ca5c0eac1b377163dd7e7a0ae1f035aaf68d793"

LOL. Weird why it kept saying that it was the wrong wallet then…. Then how do I pump the Effective fee rate?
Maaan, im learning a lot here. Taking notes in a doc for another time.
Try different outputs
You had :0 :1already.
What output do you get when running the command with :2 or :3?
it seems that it didn’t do anything with :2 or :3. But it also keeps saying that “the passed output dora’s not belong to the wallet”
🤷
One more question. I almost promise that its the last one:-)
It’s three days since I closed the channel. What happens if it never gets confirmed on the chain? Isn’t there something about it can only stay in the mempool for 14 days?
Good question. I never experienced that it took longer than 14 days. The effective fee rate of 6.00 sat/vB seems not that bad (I have seen 1!). It always stays in your local mempool. In case you restart your node be sure you do a rescan putting reset-wallet-transactions=true in your lnd.conf. Yes the location is hard to find in umbrel. It is: umbrel/app-data/lightning/data/lnd/lnd.conf.
But in your situation I would not worry too much. Just have patience 👍
