New magazine doesn't federate with Lemmy?

First of all, sorry if this magazine is not the correct place for such questions.

I "migrated" my small community over from kbin.social since, well, it's dead. The community is Greece (https://fedia.io/m/Greece) and users from other instances such as lemmy.world etc don't seem able to see any of my posts.

For example: https://lemmy.world/c/Greece@fedia.io

Any ideas for this?
