A search on !belgium@0d.gs does not find that community, but it finds a post where I can reach the community in a round-about way:
https://fedia.io/m/belgium@0d.gs
So it seems something is broken with the search. I was actually looking to reach !self@0d.gs. Searching also failed for that, so I tried manually forming this URL:
That gives a 404. It feels like a chicken-egg problem. Once I subscribe to it, it would probably be federated and perhaps searchable. But I can’t seem to reach it to subscribe without a subscription.
I can’t help meaningfully, but it is interesting to note that that community is visible from kbin.earth:
https://kbin.earth/m/self@0d.gs
This might indicate that there’s some configuration difference between Mbin running on Fedia and kbin.earth.
