Mastodon not federating to Lemmy?

Mastodon not federating to Lemmy? - Lemmy.ca

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 [https://thecanadian.social/@chimpchomp/116233903044787684] a link to the post on Mastodon, and here’s [https://lemmy.ca/post/61836481] 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?

Mastodon doesn't know to send replies to the community for distribution to the rest of the threadiverse.

Long story short if you're not on the same instance as the community, Mastodon replies to you won't make it to the rest of the threadiverse.

I experimented with a hack to see if I could fix this. NodeBB works around this by including a hidden mention to the community that Mastodon will then pre-fill in the text box, and then the reply will make it in successfully. If you have a Mastodon account try to reply to this comment, the community will be pre-filled as a mention.

Piefed, Lemmy, and Mbin will need to do this.

Does it work? Yes

Are we supposed do it? Technically no, it's easier to blame Mastodon for not doing it right.

Should we do it? Probably, yes.

@[email protected] @[email protected] @[email protected] @[email protected] I tested this. It works perfectly fine. We can implement this today and remove it when Mastodon supports threadiverse conversations better (I'll try to make that happen.)

Did you receive my email from last Thursday? Seems there might be some delivery problem.

About batched votes? Yeah I did, just haven't responded yet 👍

I was asking Rimu, but good to get confirmation that it’s working for you at least :)

Sorry - email is the channel which adds things to my todo list so when I get too busy I become avoidant about it. Just opening Thunderbird makes me a little anxious! “Ahh, yes, the app which brings more pain, here we go again”

I see, that is understandable.

Unless the person replying on Mastodon removes it of course (to save themselves some characters and because they don’t recognise it).

There doesn’t seem any functional difference between your comment (which implicitly Mentions the community), and the original post on thecanadian.social (which explicitly Mentions it). Screenies from activitypub.academy show that replies to both include both Mentions pre-filled.

thecanadian.social/@mike/116234121499688717 didn’t remove the Mention, and so the comment made it to Lemmy. mstdn.ca/@cass_m/116234270845317774 did remove the Mention, and so it didn’t.

Specifically for Lemmy btw, the reply at mstdn.ca/@cass_m/116234270845317774 demonstrates another problem - that instance requires a signed GET request for its actors, which hasn’t been fully implemented AFAIK.

Oh… That explains a lot of. Thank you for sharing the cause and the solution (^_^)

Wow that’s a really proactive response, thank you! Please keep me posted on how it goes

@julian I just had a thought! So mastodon is my main account on the fediverse right, but I use Pixelfed often, what if as a user you could embed another account in your posts on platform like you are talking about with groups so I would always recieve notifications on both. There could be some rel=me verification first of course
