Subscribed to community, but not syncing - Lemmy

The community https://lemmy.ml/c/[email protected] [/c/[email protected]] [https://lemmy.ml/c/[email protected]] 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 [https://lemmy.bestiver.se/c/hackernews]. Does anybody know how to use this (without migrating my account to another instance)?
