Git不能更新以及提交代码，提示链接超时，本地凭证无问题

1、pull时打印日志

GIT_TRACE=1 GIT_CURL_VERBOSE=1 git pull

输出日志：

从调试日志来看，Git 已经成功连接到 Gitee 服务器（Connected to gitee.com (181.76.199.13) port 443），但在 TLS 握手阶段（Client hello）之后卡住，没有进一步输出。这表明问题可能出在 SSL/TLS 认证 或 网络代理拦截 上。以下是针对性解决方案

1. 检查 Git 的 SSL 证书配置

(1) 确认证书路径是否正确

日志中显示 Git 使用的 CA 证书路径：

CAfile: D:/LifeApp/Git/mingw64/ssl/certs/ca-bundle.crt

• 检查该文件是否存在：

  ls "D:/LifeApp/Git/mingw64/ssl/certs/ca-bundle.crt"

• 如果文件丢失，重新安装 Git 或手动下载证书包。

(2) 临时关闭 SSL 验证（测试用）

git config --global http.sslVerify false
git pull

如果成功，说明是证书问题，需修复证书路径或更新证书：

git config --global http.sslVerify true  # 恢复验证

2. 排除代理干扰

(1) 检查是否启用了代理

git config --global --get http.proxy
git config --global --get https.proxy

• 如果返回代理地址，清除代理设置：

  git config --global --unset http.proxy
  git config --global --unset https.proxy
