Subscribed to community, but not syncing

The community https://lemmy.ml/c/hackernews@lemmy.bestiver.se is not syncing to this instance, even though both instances list each other as connected. I'm subscribed to the community, and resubscribed today. Posts are visible on https://lemmy.bestiver.se/c/hackernews.

Does anybody know how to use this (without migrating my account to another instance)?
