我剛剛意識到我網站的某些連結導致“502 Bad Gateway”錯誤。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。我很確定這些連結幾週前就有效了，我不知道發生了什麼。
網站https://v2a.10studio.tech/仍在工作。https://v2a.10studio.tech/#/sign?next=/包含點擊導致連結損壞的按鈕。
這是docker-compose.yml：

有人可以幫忙嗎？
PS：幾週前我在 CloudFlare 中更改了 funfun.io 的一些設定（尤其是 SSL 憑證），但我不知道是否相關。我不知道這Proxy status（DNS only或Proxied）是否有影響。

答案1
此錯誤SSL alert number 40表示您嘗試連線到需要 SNI 的 HTTPS 站點，但未傳送 SNI 主機名稱。
您正在嘗試向名為 的伺服器proxy_pass發出以 開頭的請求。但網站託管在 CloudFlare 上，因此需要 SNI 透過 HTTPS 連接到它。不幸的是，nginx 對傳出上游 HTTPS 連線的 SNI 支援預設已停用（我無法想像為什麼）。您需要明確啟用 SNI 以使用.這可以在上下文中設置，以便它適用於整個配置中的每次嘗試，或者可以僅放置在需要的特定位置。/auth/upstreamwww.funfun.ioproxy_ssl_server_name on;httpproxy_passlocation
