In the distant past, I self-hosted Tiny Tiny RSS, accessed it from a web browser and an Android phone, and liked it. I didn't have any problems with it but just never got around to setting it up again when I migrated VMs.

Now, I've been using NewsBlur (mostly on iOS, rarely on desktop) ever since Google Reader shut down. I don't have too many subscriptions but a couple folders for online comic strips, status pages or blogs of things I pay for (email service provider, etc.), and some software projects (Kubernetes, etc.).

Shameless self-plug - I'm working on a product that supports aggregating RSS feeds: https://looking-glass.app It works differently than the other RSS readers I've tried. It's in early stages, so feedback is highly appreciated.

Fan of inoreader myself.
