Can hitboxes (F3 + B) be disabled on certain servers? It wouldn't work on a certain server I joined

For some reason, F3 + B, an entirely client-sided debug command (that I use quite often actually) for some reason just wouldn't work on my friend's Aternos server. Any explanation why? Is it a thing that can be disabled now? Maybe a plugin did it? I honestly don't know (and nor does the owner)

That hitbox is Minecraft options, it doesn't even do anything affected with server. It's not even a command

I know, which is why it's so bizarre that it *only* didn't work on my friend's server. I tested in singleplayer and a different server and they both worked just fine. On my friend's, it'll say "hitbox shown" but won't actually show *any* hitboxes, which mind boggles me

and yeah it isn't a command, whoops

What type of software your friend's server use

Software?

Bukkit, Spigot, Vanilla, Modded, Banana, etc.

Bukkit or Spigot, but definitely not modded or anything else. All I know is the server has a bunch of plugins

I checked, and for some reason this may be a client side glitch.

I wish. As soon as I noticed it I logged off the server, went on singeplayer, and it was on instantly, same with other servers (completely forgot to mention this, sorry). But when I joined that server, despite it saying in text "hitbox shown". it wouldn't display a hitbox on anything (items, mobs, my player in f5). I even asked 2 other members on the server to F3 + B and they said nothing happens, but the owner said it worked just fine for him

I'll send a screenshot at some point
