View logs - Loop out transaction

Hi, I initiated a loop out yesterday but the transaction failed. I tried three times but they all failed. There was a prepayment of 30K sats for each transaction. I am trying to access the logs to find out what happened. Can anyone tell me how to access those logs. The help desk at Lightning Labs says I need to find this:
“you need to trace the Umbrel logs and look for loop daemon logs around the time you submitted the loop out.”
