我们有 kube-lego 设置，所以证书应该自动更新。它没有，根据下面的日志，到达这些站点似乎是一个问题：
time="2019-08-28T22:17:26Z" level=warning msg="authorization failed after 5m0s: reachability test failed: Get https://my.website.com/.well-known/acme-challenge/_selftest: x509: certificate has expired or is not yet valid" context=acme domain=my.website..com
time="2019-08-28T22:17:26Z" level=error msg="Error while processing certificate requests: no domain could be authorized successfully" context=kubelego
time="2019-08-28T22:17:26Z" level=error msg="worker: error processing item, requeuing after rate limit: no domain could be authorized successfully" context=kubelego
我已经研究了我可以用谷歌搜索的所有解决方案。我已经杀死了 coredns 豆荚并杀死了 kube-lego 豆荚，但它没有解决问题
