Skins don't load (cracked server)?

I run a minecraft server for cracked users

however, the skins are not loaded even by premium users.

is there a plugin or a setting I have to have?

No. You run a cracked server, i.e. A server that runs in online mode = false?

Then it is clear. No skins are loaded there, that's just the way it is. But I think I once saw that you could somehow verify yourself on a cracked server and then also had skins. Maybe there's a way to program that, but I don't know how myself. Maybe there's a plug-in on the Internet for this, or maybe the players will only be sent to non-cracked servers as soon as they are verified.

There's a server called Play.kaboom.pw and they did it too

therefore it is possible without a plugin.

Hmm… But not the skin is loaded, but a custom skin is set. You can see that you still don't have one in the tray list.

Loading custom skins is of course possible. So when you join, the skin is always loaded by the joined player

Ok, i have an idea:

first: the first solution, i will get an aternos server and configure it so that i can forward it to my server and load my skins.

The second option you just mentioned is cool but not practical, it should only be able to join certain accounts cracked
