我正在尝试简单的greenlock-express example，并且已经尝试了很多次，但是无法正常工作。我多次阅读了本教程。我创建了greenlock.d/config.json文件，它可以正常工作，因为我在输出中看到了域。
启动时，我看到：
webhook_test | Listening on 0.0.0.0:80 for ACME challenges, and redirecting to HTTPS
webhook_test | Listening on 0.0.0.0:443 for secure traffic
webhook_test | Ready to Serve:
webhook_test | ewkhrwk.xyz
但是当我通过邮递员访问它时，会得到
webhook_test | ACME Directory URL: https://acme-v02.api.letsencrypt.org/directory
webhook_test |
webhook_test | By using this software you (me@email.com) are agreeing to the following:
webhook_test | ACME Subscriber Agreement: https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf
webhook_test | Greenlock/ACME.js Terms of Use: https://rootprojects.org/legal/#terms
webhook_test |
并保持几分钟。以前，几个月前我使用greenlock时，它只是在第一次访问时就生成了证书。
几分钟后我得到
webhook_test | Error cert_issue:
