Sometimes federation takes a bit, especially from some of the instances that go down more like feddit.de
I can see the comment on the thread you linked when checking it now https://programming.dev/comment/9725576
Oh, maybe that's why sometimes there are more comments counted but they don't display. So, in theory, if I find a post where that's the case and then visit it after it's been dormant for a while, I'd see the formerly-missing comments. I'm going to test that. I hope that's the source.
That doesn't show the same comment for me, it's one of the child comments... "show context" and "view all comments" still don't show me this comment, nor does the user's profile page.
The comment language is set to german, do you have that disabled in your language settings?
https://feddit.de/ returns a server error, so it is a problem with the federation - i.e. lemmy.ml was able to pull the comment at some point, but programming.dev could not.
Federation issues like this are common in my experience, but ofc ymmv bc it depends heavily on from where to where. e.g. I am using my discuss.online account rather than my startrek.website one for similar reasons, where the latter server often randomly fails to receive or to post something lately.
How is the index page returning an error indicative of federation problems?
I've been experiencing the same for a few months now. There was one that I found in my replies that didn't show up in the original thread on my instance. I thought someone must have been aware and it'd get fixed, but maybe it's just going unnoticed by most people.
