eclair not sending any channel_update to cln after a while #2717
Comments
That's surprising, becauseI just checked that we did create a channel update for that channel (on July 17th) and we did broadcast it to our peers through the usual staggered broadcast mechanism. We refresh channel updates every 10 days (since the spec says we should refresh at least every 14 days), so I'm surprised it was somehow dropped. |
Apparently, this is the root cause of #2645 I experienced this bug as well. Fixed by nuking the network database. |
I don't think these issues are related, in #2645 it was a custom plugin that was generating invoices with invalid routing hints, that's why path-finding couldn't find a route. |
I think i kept this "broken" channel open long enough and will close it soon, if there is no easy fix. |
AFAIR the symptoms were the same (a lost channel update) and the fix was the same (nuking the network database). @evd0kim correct me if I'm wrong. |
There's no fix per se. Is I mentioned above there a home remedy: forcing your node to re-sync with the Eclair node. For Eclair it can be done by purging the network database. For CLN it can be something different. |
i already deleted the graph if thats what you mean. Didn't help. |
I can confirm I did this at least once. But I should say that Eclair have settings for whitelisting network announcements peers. So it may be that your peer intentionally ignores you. |
I noticed that my cln 23.05 node is not receiving any channel_update for 776755x557x1 anymore from the ACINQ node.
You can see that other nodes are also missing this channel_update here: https://mempool.space/lightning/channel/854051154469650433
I opened an issue on the cln repo first, but apparently it's the responsibility of the eclair node to send the channel_update so i hope this is the correct place to raise the issue. I already tried deleting the gossip store and restarting.
I remember that the channel did not miss the direction from ACINQ in the beginning and i have opened a second channel which is also fine for now.
