ubuntu - 无法解决letsencrypt错误，原因未知

问题描述

我想使用 Let's encrypt 颁发 SSL / TLS 证书。我更改了 Nginx 设置，安装了 certbot 并尝试运行它。但是，错误的原因尚不清楚，也无法解决。

我使用 Ubuntu、Nginx、Gunicorn。服务器是 DigitalOcean。

这就是我认为的原因。请告诉我是否还有其他原因。

这是我执行的命令。

sudo certbot certonly --webroot -w /var/www/letsencypt/ -d letyu.com

/var/log/letsencrypt/letsencrypt.log
