My friend can't join my Hamachi Lan world with his Minecraft Cracked version?

All my friends who own the full version can join me easily, but the one with the cracked version is not. This is the error code: Login Failed: Access Token can't be null or empty

Do I have to change something in the settings somewhere?

NOTE: This is not a Hamachi server but they join me by Lan please note.

He needs a valid account. You have to buy it nunmal.

I know that. The question was rather how, despite the cracked version, I could enable him to join.

No, because you need a valid account. But you can make a free online server on Aternos on which also Cracked users can join.

Aternos has been waiting too long for me.

At the moment, at least for me, it does not last a minute. Already over 2 weeks.

That's because the login data is matched with Mojang when logging in. If UserId and Name do not match the account list of the purchased accounts, then the registration is not possible…

Right, blatant. Thanks, they seem to have upgraded the servers.

You have to put the server on Cracked, or he just uses MCLeaks

Go to the server.properties

and then you do online-mode = true → online-mode = false

But it is a private world. Is that still possible with the server properties?

Do you mean localhost? Then yes

Where can I find the server.properties?

In the main directory of your server…

Maybe you should rather leave hosting…
