I see. it's my list to adjust sth.
1. I added it in packet_db.txt
packet_db_ver: 56
//packet_db_ver: default
packet_keys_use: default
// 2017-01-25aRagexe
packet_ver: 56
packet_keys: 0x066E04FE,0x3004224A,0x04FF0458
0x0438,7,actionrequest,2:6

2. I also adjusted src/config/core.h
/// Comment to disable the official packet obfuscation support.
/// When enabled, make sure there is value for 'packet_keys' of used packet version or
/// defined 'packet_keys_use' in db/[import/]packet_db.txt.
/// This requires PACKETVER 2011-08-17 or newer. //#define PACKET_OBFUSCATION
3. src/common/mmo.h
#ifndef PACKETVER
#define PACKETVER 20170125
//#define PACKETVER 20120410
4. src/common/utils.c
else if(date < 20151104) return 54;
else if(date < 20160203) return 55; else if(date >= 20170125) return 56;
else return 30; //default
5. src/map/clif.h
enum { // packet DB
MIN_PACKET_DB = 0x064,
MAX_PACKET_DB = 0xAFF,
MAX_PACKET_VER = 56,
MAX_PACKET_POS = 20,
then I compiled it again.
