Read through this a couple days ago but now going through my server to check, is the setting ‘List of IP addresses and networks that are allowed without auth’? Because I’m on the latest linuxserver docker image and still have that setting in the server network settings.
I use Kavita since I don’t get audiobooks and found out about it before ABS. I convert amazon bought ebooks to epub using calibre and put them on my unraid server to get picked up by kavita. Any epub can be emailed from kavita to my device.
