DomainRecordNotBelongToUser

用了几天都是正常解析的。今天执行 sudo python ./ddns.py 时出现这个错误讯息：

[INFO] current public ip is:180.108.xxx.xxx, server ip is:121.239.xxx.xxx Http Status Code:400 {"Code":"DomainRecordNotBelongToUser","HostId":"dns.aliyuncs.com","Message":"The domain record does not belong to this user.","RequestId":"357B62E7-B29D-4581-8A74-EF1E5DCD3642"} 2016-12-09 14:34:49 [ERROR] Failed to sync the current public IP for record:DomainRecord1

我确认过 Access Key ID 和Accuess Key secret 都是正确的，请问是什么原因呢？
