Mastodon not federating to Lemmy?

I’m not sure if this is the wrong place to post this; my apologies if it’s not.

Anyway, I have an inquiry about Mastodon replies seeming to not post to show up on Lemmy.

Earlier today I made a post on Mastodon and made it post to Lemmy as well, by @ing the community I wanted it to appear in. Here’s a link to the post on Mastodon, and here’s how it showed up on Lemmy. At first, everything seemed to work fine.

But something I noticed is that, though the Lemmy comments were visible to me on Mastodon, the reverse was not true: most of the Mastodon replies were not visible on Lemmy. So there seems to have been some federation issues there.

So my question is, does anyone know what caused this and if so how I can fix it?

If I had made this post on kbin would the lemmy and mastodon users have been able to interact with one another?

It’s pretty inconsistent, depends on what the people running the site are doing, and I’m not certain if unfederated Mastodon instances’ posts on a federated Mastodon instance mentioning a community would show up, will test it. Seems like the Palestine comm and other stuff that is really consistently popular on both sides for years is what works reliably. Plus it depends on Mastodon fork. Misskey would have no problem federating with Lemmy if not for one tiny bug, but the forks like Sharkey and Iceshrimp already solved that. It’s just that nobody except for me and like 37 other people know they exist.

You mentioned K/Mbin and I honestly find it a bit distasteful, as representing what should really be the same kind of post-reply format (the retweet accounts represent comms or rss feeds etc perfectly, I even use them for scraping imageboards and Telegram, these sites may have different UI but they’re almost the same format) in a whole separate thing just feels really clunky and the magazines are weird—sorry if that makes you mad because it really fits your workflow. Wish there was just more basic consistency between the platforms since users could share information regardless of whether they have Twitter or Reddit brain 😁

i believe there is a one-way mechanism for twitterverse posts to be used an inbound content stream for lemmy (like rss ) but thats it… one direction.

The Lemmy posts were showing up as replies to my Mastodon post. And some of the Mastodon replies were showing up in Lemmy. So it does seem to go both ways, its just inconsistent

It’s more likely that the instance hosting the community would make the most difference. Try a PieFed community if you’re interested.

unless somethin new has happened, lemmy doesnt fully federate to mastodon/the twitterverse. interaction is very limited.

its one of the reasons i use mbin instead of lemmy

I always an avid user of piefed.ca but I had to quit because most of my comments weren’t federating anymore due to some corrupted data issue

lemmy does not federate with mastodon/the twitterverse..

i dont think theres anything you can do to make that happen short of some janky bridge.

i subscribe to lots of peeps from the twitterverse.. i can reply to/comment on posts, see other comments, upvote/boost, etc.. kbin is dead long live mbin.

If you use Misskey or whatever it calls itself now, it works well with Mastodon and okay with Lemmy.

Yeah… That’s a common fédération issue. I haven’t properly investigated but a hypothesis might be that the account that commented are on instances not federating with the Lemmy instance.

Here a community for you to do more test : !testfediverse@jlai.lu

If I had posted this on Miskey would that have allowed Lemmy users and Mastodon users to interact?

Good to know thank you! Piefed seems to be doing a lot to help the fediverse grow, so thank you for your service 🫡

Now that the issue is fixed I need to make a new account or will it work with the old account too? Also I noticed that my profile photo from my old account isn’t federating haha, but that’s a very minor issue so I’m not too concerned about it haha

Eh. Not really very effectively. Misskey does a half decent job of talking to Mastodon and Lemmy, but Lemmy and Mastodon do a pretty poor job of talking to each other and I think Misskey is more compatible with Lemmy than Lemmy is with Misskey, if that makes sense.
