Maybe Firewall just needs an additional reboot
yes I've tested it and logging can be done.1. Stop the service from the plugin UI.I didn't find it possible to control it from the command line as per AdGuard docs ie. ./AdGuardHome -s --service VALUE https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#configuration-file maybe I misread the command syntax.2. Modify your yaml: /usr/local/AdGuardHome/AdGuardHome.yamlPupulate the parameter log_file:I used log_file: /var/log/AdGuard.log3. Start the service from the plugin UI.Note: by default the parameter and value "verbose: false" gives some logging but not a lot. Changing it to true is the oppossite, as the name implies, verbose. So you might want to only keep it to true for a short time.
