watchtower and linuxserver images

[StancuFlorin]

This is the first time I am trying to setup Watchtower and I have some problems with the linuxserver images. unRaid is saying that there is a new version avaiable, but Watchtower is unable to update the containers.

the container is basically started like this

docker run
  -d
  --name='watchtower'
  --net='bridge'
  --pids-limit 2048
  -e TZ="Europe/Athens"
  -e HOST_OS="Unraid"
  -e HOST_HOSTNAME="Tower"
  -e HOST_CONTAINERNAME="watchtower"
  -e 'WATCHTOWER_NOTIFICATIONS'='shoutrrr'
  -e 'WATCHTOWER_NOTIFICATION_URL'='telegram://dsa@telegram/?channels=dsa'
  -e 'TZ'='Europe/Bucharest'
  -l net.unraid.docker.managed=dockerman
  -l net.unraid.docker.icon='https://containrrr.dev/watchtower/images/logo-450px.png'
  -v '/var/run/docker.sock':'/var/run/docker.sock':'rw' 'nickfedor/watchtower'
  --schedule "0 0 8 * * *"
  --cleanup
