I’ve been running my node for over a year and keep it up to date with whatever updates are shown in Umbrel. Have had 30-50 channels open and rarely had any problems.
Probably 2 months ago, I did my last round of channel openings and had one channel that had a very low opening price, which would therefore take 24+ hours to open. Had done this many times before and was happy to wait it out.
Recently, I went in to clean up some open channels where the other nodes were down for 1+ month and noticed that this one channel was still not open. I went and initiated five more channel opens to five other nodes and waited a few days, but none of these channels are now open.
Here’s a screenshot of a few of them with the problematic channel having no name:
Just so I understand- are these other channel openings at a low fee rate, similar to the first one you were having an issue with?
If so, it is quite easy to bump the channels with a CPFP transaction.
I would suggest downloading ‘Ride The Lightning’ from the appstore. From there you can navigate to the following menu on the app. I don’t have any LND channels at the moment, but you will hopefully see your pending transactions there. Ride The Lightning will then let you create a CPFP transaction that bumps the fee of your old transaction.
Unfortunately fees are pretty high right now, so I would suggest using a free rate of around 50sats/vB for this channel to open tonight. 40sats/vB at the lowest.
Then if you locate your low fee channel, it will contain a tag ‘channel point’. The index value is at the end of this tag, and while it is a little confusing, the index value of the change output is the opposite of that number. ie if channel output ends with a 1, your index value of the change output is 0.
Let me know if that helps!
