Some Error in ttyhstore

Hello!

You need to create "files" directory, and "mutables.list" in version folder. Then call collect. See example here: http://store.ttyh.ru/default/1.11/

Simple instruction for local version is here: https://ttyh.ru/viewtopic.php?pid=3840#p3840

Rewrite .sha1 file next to lib with actual checksum.

Mojang used weird skin signing scheme. AFAIK it's outdated already, but we did not make any related changes in master...

Well, you need valid keypair in authlib and on master server to make skins work. We use this one.
Place key.pem to master directory and replace yggdrasil_session_pubkey.der in authlib jar.

Are you sure that this uuid is correct? Blank answer for nonexistent uuid is normal there.
Check master error log as well.

I ust this trigger to generate UUID and Access Token, is it correct??
When user register on the web and it will work.

CREATE TRIGGER `master` BEFORE INSERT ON `users`
 FOR EACH ROW BEGIN
SET NEW.accessToken = UUID();
SET NEW.clientToken = UUID();
END

I have modify the php and change table "players" to "users" because I want it to synchronize with forum
