Hello,
Think with new version, problem with the "FLOOD_PASSWORD" variable :
WARN[0000] The "FLOOD_PASSWORD" variable is not set. Defaulting to a blank string.
$ cat .env.custom | grep "flood"
# Flood Password for Deluge RPC daemon
FLOOD_FLOOD_PASSWORD=xxxxxxxxxxxxxxx
#FLOOD_FLOOD_OPTION_HOST=deluge
FLOOD_DELUGE_HOST=deluge
