I am pretty sure & only puts the command in the background - it does not detach it (so it closes when the terminal window closes)
I do not understand who disown and nohup do not work. Have you looked at the nohup.out file it should create?
You can also try putting brackets around the command like so
It works for me, but I use zsh so I am not sure if it works on bash as well.
