invalid connection handle

I started scripting a fresh new TDM script from 0 and I wanted to try out the bcyrpt hashing alg and everything went fine I created a register/login system but when I wanted to test it next things happend:

myScript:

public OnPlayerConnect(playerid) {
?? ?new query[256];
?? ?mysql_format(SQL, query, sizeof query, "SELECT * FROM `players` WHERE `name`='%e' LIMIT 1", GetPlayerNameEx(playerid)); // 9
??? mysql_pquery(SQL, query, "OnAccountCheck", "i", playerid); // 10
??? #if defined reg_OnPlayerConnect
??????? return reg_OnPlayerConnect(playerid);
??? #else
??????? return true;
??? #endif
}
#if defined _ALS_OnPlayerConnect
??? #undef OnPlayerConnect
#else
??? #define _ALS_OnPlayerConnect
#endif
#define OnPlayerConnect reg_OnPlayerConnect
#if defined reg_OnPlayerConnect
??? forward reg_OnPlayerConnect(playerid);
#endif

The errors I get in mysql

[INFO] changed log level from 'warning, error' to 'debug, info, warning, error'

EDIT: I use R41-4 and this happens after OnGameModeInit, and my connection is successful
