看你的日志，连接失败的核心原因是远程服务器在下载 TRAE 服务端组件时，访问 CDN 地址返回了 404 错误。

这种情况通常是因为远程环境在下载安装脚本（install.sh）或服务端包时，由于网络环境或特定版本的路径匹配问题导致下载失败。针对这个问题，建议你尝试以下步骤：

核心方案：开启增强兼容模式

这是解决此类“VS Code 能连但 TRAE 报错 404/超时”最有效的方案：

在 TRAE 中打开设置（快捷键 Cmd/Ctrl + ,）。
在搜索框输入 remote.SSH.enhancedCompatibilityMode。
勾选 Remote.SSH: Enhanced Compatibility Mode 选项。
彻底关闭当前的远程连接窗口，然后重新尝试连接。

为什么会出现这个问题？

TRAE 和 VS Code 虽然都使用 SSH 连接，但 TRAE 需要下载自己定制的服务端组件（Trae Server）。日志显示你的远程机器在尝试从 lf-cdn.trae.com.cn 下载时失败了。开启“增强兼容模式”后，TRAE 会调整连接和下载策略，通常能绕过这类路径或网络握手问题。

论坛相关讨论

我在论坛也找到了几个和你遇到类似报错（SSH 404）的讨论，你可以参考下：

Trae的SSH登录错误，服务器404了 https://forum.trae.cn/t/topic/15887/2
这里SSH连接出现问题，curl返回404 https://forum.trae.cn/t/topic/13359/20

如果勾选增强模式后还是不行，建议检查下远程服务器是否设置了不通的代理，或者尝试在远程机器上执行 curl -I https://lf-cdn.trae.com.cn 看看是否能正常连通外网。

希望这能帮到你！如果还有报错，可以再把新的日志贴出来哈

重启一下服务器试试

之前是正常的吗？看下环境有没有发生变化。
