At your end

[Ju]

How's everything going at your end?

Can I use "on" to replace "at"?

Thank you.

You can, in BrE, remove the preposition completely.

How's everything going your end? :tick:

Not in BrE. I cannot say for other variants, but I have never come across it.

"How's everything going on your end?" sounds OK in American English. It's casual usage.

 

[Tdol]

That's what I was wondering.

I just heard a commentator use it on CNN. It could be coincidence or, more likely, listening out for it.
