Hello, not to derail the topic. I just had FTL go offline a moment or so ago and a reboot fixed it.
Maybe, if possible, is there any way a command similar to 'pihole restartdns' be implemented for FTL?
Please investigate in your /var/log/pihole-FTL.log if there is any indication for why FTL goes offline (it will log if it e.g. crashes). If you don't know how to do it, run
pihole -d
go generate a debug log, agree to upload and provide the token.
Are you sure that your are on the latest version of FTL? Should be v2.7.3 if I'm not mistaken.
