I can access c/world on lemmy.world without problem:
lemmy.dbzer0.com/c/world@lemmy.world
But I cannot access c/whatstheword:
lemmy.dbzer0.com/c/whatstheword@lemmy.world
It seems unlikely that this specific and innocent community is blocked on either instance.
What's going on here?
i don't know about lemdroid. federation could be backlogged for aforementioned reasons.
the link you gave works fine for me in Firefox: clicking, dragging or pasting. the 404 likely indicates that lemdroid hasn't discovered that community yet; probably because it's still waiting to finish asking lemmy.world about it.
are you sure about that? on FF if I click on the first part of the link it redirects me to lemdroid, but clicking the part after the /c/, redirects me to dbzer0. Also different part of the link lights-up when hovering over it
