七牛云存储备份不能用了吗？

为什么密钥都输了，一直在响应，也不提示成功。。。卸载重装也不行，配置填的都对之前用过。

面板版本是？

最新版，刚装的

版本5.8.7

？？？？？？？

我之前centos 6装python2.7 出现此问题，翻了很多文章最后翻到河妖自己说的让人要python2.7就用centos7 吧。不这样的话我所有服务器装最新版宝塔全部访问不了面板，七牛、FTP等备份全部不能用。
现在全部装centos7了，面板ok，七牛和FTP一开始也能用，但没多久看日志就一直出现报错，报一报又说已备份、已清理过期文件.... 五月底就是因为这个问题害我丢失了几天的数据库备份，造成很大麻烦。

七牛云报错信息如下：
