DRAWS™ Manager

DRAWS™ Manager does not need to run all of the time. It is a setup tool, then you can shut it down.

sudo systemctl stop draws-manager

and to prevent it starting up on next reboot

sudo systemctl disable draws-manager

Or you can move it to a different port, as documented here

If you want to set the port, edit /etc/default/draws-manager and add a line with the port number, e.g. PORT=80 (it defaults to 8080)

And restart.

sudo systemctl restart draws-manager
