更新letsencrypt免费ssl证书时遇到的问题

linux下运行命令 ./certbot-auto renew 更新Let’s Encrypt安全证书时抛出以下错误:

Attempting to renew cert (wlsf.tpsion.com) from /etc/letsencrypt/renewal/wlsf.tpsion.com.conf produced an unexpected error: Failed authorization procedure. wlsf.tpsion.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://wlsf.tpsion.com/.well-known/acme-challenge/ZwCl6daUNZ_i9erH4TX73CiCBkv3ITrO0mEM-ZNidOE [120.24.75.7]: "\r\n404 Not Found\r\n\r\n

404 Not Found

\r\n
". Skipping.

 

解决方法:在nginx的conf目录下配置域名wlsf.tpsion.com的非安全链接(http)访问,配置好后运行service  nginx  reload  更新配置, 再运行./certbot-auto renew 更新安全证书。
