Im a bit confused. In a post (made on lemmy.ml) I replied to a comment (from someone on fmhy.ml) and my comment is not showing on sh.itjust.works. I am registered on lemmy.world As far as I understand these instances are connected. Is it taking a long time to aggregate ? Does it have anything to do with language selection? I have undetermined,greek and english selected. Here is the post but it is in greek so it may be a bit confusing.

At least one person has to subscribe to that instance from the instance that you want synced, then it starts federating. Unfortunately, it does not update comments/posts that have been made before this first subscription happened. What you can do is manually trigger a sync - to do this, you need to copy the link of the posts/comments and post them in the search bar of the instance you want to have synced. However, this does not work for replies of comments (because the link is for the thread). I hope this could help you.

Im not sure I understand, are you saying the problem is that no person from sh.itjust.works is subscribed to lemmy.ml/c/Greece so there is no federation between them ? Or just in general from sh.itjust.works to lemmy.ml ? This seems unlikely since they are relatively large. Here is the post from sh.itjust.works instance I am not sure this tracks. I might have missed something.

Yes, at least one person from sh.itjust.works needs to go to https://sh.itjust.works/c/greece@lemmy.ml and click on subscribe. Then everything starts federating from this moment onwards. If you want to see past posts/comments you need to manually search for them on https://sh.itjust.works. If you want the comment https://lemmy.ml/comment/760707 to be displayed, you need to paste this link (after subscribing) to the search field of sh.itjust.works. However, as I said, it does not federate replies of comments because the link is just for the comment. I guess that is a bug/limitation of lemmy, see https://github.com/LemmyNet/lemmy/issues/2241#issuecomment-1112505474

So lemmy assumes there is no need to federate stuff to instances if nobody on those instances is subscibed to the community. Basically the users of the instance dictate what gets fedaterated to it. The partial existance of https://lemmy.ml/comment/760707 still is confusing to me though. If the parent got federated why not the replies? Maybe someone subscribed from sh.itjust.works and searched fot it?

The fact that children/replies to comments are not fetched seems like a bit of an oversight but it's understandable since this would likely not be a big problem with users in the high hundereds.

I think it works for replies of comments.. you need to copy the link from the federated icon next to the chain icon. That is the correct link that should be posted in the instance you want synced.

It does work with that link. It still seems weird that the parent comment was federated (so someone either subscribed and then unsubscribed before I replied or searched for it?) but thanks for helping me out. I think I understand things a bit better now.
