Since you’re using prowlarr, I recommend adding as many as you can. You’ll get some stall, but that’s the price you (don’t) pay. If you have the time, choose several baseurls for the failing indexers so you can get as many as possible.

I thought tools like OnlyOffice filled in that gap. Nice to see an alternative.

Bravo! CosmOS does look pretty nice. If I had better hardware, I might try something like that. Right now I’m using Fedora Server because of the SELinux, copilot, and podman support out of the box.

I’ve noticed that, too, about the community. I think part of the reason for the friendliness is a desire to see the community grow. Self-hosting feels very grassroots.
