I have installed Pluto for Channels on a Synology Docker. I have Channels DVR running on windows. I have set up Pluto for Channels as a source. The Pluto channels play correctly, however the EPG guide gives the following error "Failed to download XMLTV-Pluto: open Http://192.168.1.133:5886/epg.xml: The filename, directory name, or volume label syntax is incorrect."
Looks like you used Http instead of http
Silly mistake, Thank you!
