I got this message:
I tried looking in the logs. Just prior to the channel closing, seems like there was a temporary network issue and the re-establishment message wasn't received by your node. Waited 5 minutes for a reply before our nodes retried (successfully) to re-connect. But I guess by then it was too late, the channel was already closed. What do you logs say?
