I really like Kavita. I started using it just a few weeks ago in an effort to expand my media library. It’s running alongside my video media library.

I love that it’s a web reader, but I’m excited for the app to come out. That would complete the experience for me as I’d rather have downloads managed by an app than have to handle the files on my local device.

Fwiw he wouldn’t get a public key password denied type error if he wasn’t able to at least reach the target, to my knowledge.

Check your logs /var/log/auth.log. You can pipe grep it to search by IP or just try to connect then quickly check. That might give you more insight that isn’t being provided to the remote client (windows).
