Indi Web Manager auto start problem - by: gmck

Hi,
I have followed the instructions on the tutorial for installing Web Manager to the letter.

If I start it manually using:
cd servermanager
python drivermanager.py
It runs fine.

If I setup the auto restart as per the tutorial and run
sudo systemctl status indiwebmanager.service
I receive the following message:
indiwebmanager.service - INDI Web Manager
Loaded: loaded (/lib/systemd/system/indiwebmanager.service; enabled; vendor preset: enabled)

Can anyone help please? Not an experienced Linux user.

This is on a laptop configured with the latest Mint Cinnamon 64 bit distribution.
All my Indi devices run perfectly when connected to this laptop. I would like to connect to the laptop remotely - hence the desire to austostart Indi Web Manager.

cheers
Gary
