Duplicati as an Ubuntu server service listening on a specific ip address/interface

I need to install Duplicati as a systemd service on several Ubuntu servers (18.04), so ​​that the WEB UI is accessible on the network and I can manage the backups for each server from my workstation.
How can I configure the Duplicati service so that it is listening / binded to a specific IP address?
At that moment the service is listening on port (localhost). How do I change this setting?
I’ve already tested the headless configuration (sudo duplicati-server --webservice-interface=) and, of course, it works. But I need to use Duplicati as a service.


Welcome to the forum!

You can edit /etc/default/duplicati so that the option line looks something like this:
DAEMON_OPTS="--webservice-interface=any --webservice-port=8200"

Then restart the service for the change to go into effect:
# systemctl restart duplicati

Perfect! it works like a charm.
Great job.
