August 14, 20241 yr Author Here you go and thanks. Sorry pretty new to tower-diagnostics-20240813-2132.zip. Well I have had it for a while without issue. This is my first that has got me scratching my head and frustrated. I know it will be something simple and I am just missing it

August 14, 20241 yr Community Expert Solution All errors were correct, that's good, recommend resetting the stats and monitoring the pool for any future issues. To recreate the docker image: https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file Then: https://docs.unraid.net/unraid-os/manual/docker-management/#re-installing-docker-applications Also see below if you have any custom docker networks: https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks

Thank all of you so much.
