与服务器的点点滴滴

2020/11/24 服务器炸了之后, 服务器日志会出现
[error] 1786862#0: *11701 upstream timed out (110: Connection timed out) while connecting to upstream, client: 120.236.146.43, server: www.bug-hunter.site, request: "GET /templates/guides-2/1/assets/images/i8homem-106.png HTTP/1.1", upstream: "https://106.75.36.64:443/templates/guides-2/1/assets/images/i8homem-106.png", host: "www.bug-hunter.site", referrer: "http://www.bug-hunter.site/templates/guides-2/1/assets/stylesheets/index.css?_t=1606011012"

核心是这句
(110: Connection timed out)
