Liftoff has an all instance view you can enable if that is what you are looking for and don’t mind using an app

The url’s above should be correct

I had to be logged in to find it on my instance otherwise it only showed your comment when I searched it

I logged out specifically to test but since I don’t have an account on your instance I can’t guarantee the same results I have gotten

Actually I just got it to pull up without being logged in on your instance

Based on the url you pasted in it looks like you are trying to sort to communities, currently the communities sort is broken

You will need to sort by all and the copy in !kde@lemmy.ml or if that doesn’t work you can also try copying in https://lemmy.ml/c/kde
