我的模型对话是可以的

[dosubot]

你的知识库问答和 RAG 功能报错（如 Client.init() got an unexpected keyword argument 'proxies'、'NoneType' object is not iterable、API未能返回正确的JSON 等），根本原因是 httpx 库的版本过高（0.28.0 及以上），新版 httpx 已经不支持 Client 初始化时传入 proxies 参数，导致相关 API 客户端初始化失败，进而所有知识库相关功能都无法正常工作，而普通模型对话不受影响。

解决方法：
请在你的 chatchat 环境下执行以下命令，将 httpx 降级到 0.27.2，然后重启服务即可恢复正常：

pip install httpx==0.27.2

如果降级后还有问题，可以检查下系统或虚拟机的代理环境变量（如 http_proxy、https_proxy、all_proxy），确保没有被错误设置。

还是报错

[dosubot]

你的新报错 “Invalid port: ':1'” 是因为 no_proxy 环境变量中 IPv6 地址（如 ::1）没有加中括号，导致被错误解析为端口号。解决方法：

1. 检查你的 no_proxy 环境变量，把其中的 ::1 改成 [::1]，即：

   no_proxy=127.0.0.1,[::1],localhost
   

2. 修改后，重启 chatchat 服务。

同时建议检查 .env、config.yaml 等配置文件，以及启动参数（如 --xinference-endpoint），确保没有端口被错误设置为 :1 或其他非法值。

详细解释和官方 issue 见：相关说明

如修正后还有问题，可以贴下你的 no_proxy 和 API base_url 配置，便于进一步排查。

这样设置后 no_proxy=127.0.0.1,[::1],localhost
直接模型对话都不行了

[dosubot]

你的 no_proxy 设置 no_proxy=127.0.0.1,[::1],localhost 理论上是正确的（IPv6 必须加中括号），但你遇到 httpx.InvalidURL: Invalid port: ':1]' 报错，说明某处配置依然有问题。

请按以下步骤排查：

1. 检查 .env、basic_settings.yaml、model_settings.yaml 等配置文件，确保 API_SERVER、api_base_url、public_port 等端口号没有被设置为 :1 或空值，必须是有效端口号（如 7861），不能有多余的冒号或中括号。参考正确写法：API_SERVER 配置示例。

2. 检查环境变量，确认没有 http_proxy、https_proxy、all_proxy 被设置为影响本地请求的值。

3. no_proxy 推荐设置为 no_proxy=127.0.0.1,localhost,[::1]，顺序无关，但必须用中括号包裹 ::1，不能写成 ::1 或 [:1]。

4. 修改后，重启 chatchat 服务。

如果还有问题，请贴出你的 no_proxy、API base_url 及相关配置内容，便于进一步定位。
