Whilst using Duplicati on a headless VM server I had issues finding how I could connect to the GUI remotely. Here are the steps I took to configure it correctly:
Go to the systemd service file for Duplicati
sudo vim /lib/systemd/system/duplicati.service
Change the ExecStart line to the following:
ExecStart=/usr/bin/duplicati-server --webservice-port=8200 --webservice-interface=any
Restart the service:
sudo systemctl restart duplicati.service
You can now connect to the Duplicati GUI externally via prot 8200:
{your ip}:3000
Pretty simple really but as with always it took me a while to Google this information so hopefully this will make someones life simpler, if that’s you please comment below or share this post.
