I restarted my Start9 node (through the system option) and now Lightning doesn’t seem to want to restart and showing in the logs :
2025-10-06T18:16:45-04:00 2025-10-06 22:16:45.807 [WRN] BTWL: Received non-standard input sig= “A string of characters”, witness=[0000000000000000000000000000000000000000000000000000000000000000]
and it just keeps repeating for hours. I have a few open channels, what should I do?
One of the issues in not providing fuller logs is that there’s no context. I assume somewhere nearby in the logs it identifies the peer that is sending you this malformed string. Most likely they are having technical issues, most likely they are a peer you don’t have channel with. If you do have a channel with them, I’m not sure if their misconfiguration is a particular risk to you or not.
Also, for what its worth, warnings aren’t errors.
The problem was it seemed like it was stuck in a never ending loop which kept my LND node from being seen online for over a day.
I checked the channels list and was still intact, tried restarting the node a few times, but it didn’t change anything. Then I tried to block internet access and then connecting again and after doing that it triggered a pruning which then the warnings stopped and LND was able to start again. Never had this in years of running LND. I was about to try a manual pruning but it got triggered automatically I guess.
Now however I am missing liquidity, I’m thinking of trying to reset wallet transactions to trigger a rescan and hopefully find what is missing, but will let the node run for a while before trying that I think. Unless there’s something I should do?
