This. Almost all posts or comments are about "there is no new posts". The fediverse must grown before one can view different posts in any lemmy instance. We need to create content, share our thoughts, pics, a link to some news or articles, or just ask a question.

Try clicking in “subscribe pending” to undo the request, then click in “subscribe” again. It worked for me with some communities from lemmy.ml

If you have the knowledge or want to learn about it, and you are willing to deal with these tasks (configuring the system and keep it updated), the DIY approach makes sense.

I was on that situation some months ago, and I didn’t want to spend time in system maintenance, so I bought a NAS device.
