Lumen QUEUES on Ubuntu via screen

I have been facing an issue of not being able to start queues that are deployed on our staging server and there is no one at the office to do this. Below is a list of commands to mention a few that I executed:

luyanda@devbox: screen -d -m sh -c "php artisan queue:flush"
luyanda@devbox: screen -r -S 2232 -d -m -c /dev/null -- php artisan queue:flush >> /home/luyandasiko/screen.log
screen -r 19167 -p0 -x stuff "free -g; php artisan queue:flush"

None of these commands seem to work. How can I run queues behind the screen session on Ubuntu?
