某些页面返回“502 Bad Gateway”错误

772

我刚刚意识到我网站的某些链接会导致“502 Bad Gateway”错误。例如https://v2a.10studio.tech/10studio/auth/google、https://v2a.10studio.tech/auth/google、https://v2a.10studio.tech/10studio/auth/microsoft、https ://v2a.10studio.tech/auth/microsoft。我很确定这些链接几周前有效，我不知道发生了什么。

网站https://v2a.10studio.tech/仍在运行。https://v2a.10studio.tech/#/sign?next=/包含点击导致链接断开的按钮。

这里是docker-compose.yml：

        # These three lines added as per https://github.com/socketio/socket.io/issues/1942 to remove socketio error

        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection "upgrade";
    }
}

有人可以帮忙吗？

PS：几周前我在 CloudFlare 中更改了 funfun.io 的一些设置（尤其是 SSL 证书），如果它相关，我不知道。我不知道这Proxy status（DNS only或Proxied）是否有影响。

该错误SSL alert number 40表示您尝试连接到需要 SNI 但未发送 SNI 主机名的 HTTPS 站点。

您正在尝试proxy_pass向/auth/名为. 但是这个站点托管在 CloudFlare 上，因此需要 SNI 使用 HTTPS 连接到它。不幸的是，默认情况下，nginx 对传出上游 HTTPS 连接的 SNI 支持被禁用（我无法想象为什么）。您需要为与上游的传出连接显式启用 SNI 。这可以在上下文中设置，以便它适用于整个配置中的每一次尝试，或者可以仅放置在需要它的特定 s 中。upstreamwww.funfun.ioproxy_ssl_server_name on;httpproxy_passlocation
