My Game Profile Builder is not working?

How is that I use a Game Profile builder and the Game Profile buillder does not work I think it is due to the service link https://sessionserver.mojang.com/session/minecraft/profile/%s?unsigned=false

The statement "does not work" is very helpful. Are there any errors? And what do you mean by that you think it is the service link? You mean about the% s? This represents a string that is passed at the end of the method, that is:

methodenName ("fff.cf/%s.png", pictureUrl);

That would look like this and is correct.

Yes the link does not work

What do you mean by "the link doesn't work"? % S uses the player's UUID, but the '-' are removed, so that in the end the UUID looks like this:

f33h379wb37heu628

and not like this

So if you enter this into the browser, an error occurs that worked about 6 weeks ago.

That comes as an error

Oh, this error. Yes, unfortunately I have already experienced it. Unfortunately I haven't found a working GaneProfileBuilder anymore. Instead, you could directly connect to the Mojang server, read out the entire JSON content and then split it. I think you want to do Skin Value & Signature for a nick plugin, don't you?

Yes you are right xD
