fail to config .json of shadowsocks

[netsupcloud]

• panel's script will add aes-128-gcm in xray_ss_method in mysql's database
  -i fixed it by add it under settings in json file like "method": "aes-128-gcm" also "password": "somepasswd".
  and so in mysql's database "method": "aes-128-gcm" also "password": "somepasswd" under settings are lost and developer missed them
• without these xray's SS cant run
