ssl - 查找丢失的 TLS 密码

Question

我在 traefik 代理后面运行 gitea。一切正常，除了 git push/pull 到这个 git 服务器。http webfrontend 也可以正常工作。

一旦我想克隆存储库，就会出现gnutls_handshake()错误。但是，如果我更改密码或切换到 TLS 1.1，我没有问题。如何找出 git 客户端 ( version 2.30.2) 想要使用的密码？

客户端上的 OpenSSL 版本（debian 靶心）：OpenSSL 1.1.1k 2021 年 3 月 25 日

traefik 使用以下密码：

tls:
  options:
    default:
      minVersion: VersionTLS12
      cipherSuites:
        - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
        - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
        - TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
        - TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
      preferServerCipherSuites: true
      curvePreferences:
        - CurveP521
        - CurveP384
      sniStrict: true

gnutls-cli-debug 的输出：
