Updating DNS to error code: 1020

[Latezly]

我是在crontab里做的定时任务
*/5 * * * * cf-v4-ddns.sh >> /home/latezly/cf-ddns.log 2>&1

刚开始启动的时候一直是正常的
过了一段时间就开始报这个错误

Updating DNS to error code: 1020
Something went wrong :(
Response: {"result":null,"success":false,"errors":[{"code":9005,"message":"Content for A record must be a valid IPv4 address."}],"messages":[]}

期间偶尔也有一段时间又恢复正常了
