[jamesxia1988]

问题描述

今日（2026-08-18）通过 MiMo Token Plan API 调用时出现 APIConnectionError，完全无法连接到模型提供方。此问题在近几天反复出现。

错误信息

今天（08-18）

APIConnectionError: Hermes can't reach the model provider. You may be offline.
base_url: https://token-plan-cn.xiaomimimo.com/v1
model: mimo-v2.5

连续 2 次重试均失败。

昨天（08-17）

BadRequestError 400: finishConnect(..) failed: Connection refused: 
  s-20260727160441-tdhjg.abcstackcn-nx-prod-cloudml.xiaomi.srv/10.137.1.77:80

TimeoutError: Non-streaming API call timed out after 90s

08-14

TimeoutError: Non-streaming API call timed out after 90s

环境

• API 端点: https://token-plan-cn.xiaomimimo.com/v1
• SDK: openai Python SDK (OpenAI 兼容模式)
• 其他 API（如 Anthropic）同时段正常，排除本地网络问题

备注

400 错误中暴露了小米内部 CloudML 服务地址，疑似后端负载均衡或服务发现故障。失败集中在下午/晚间高峰时段。

Hi, thanks for the detailed report.

About this project: MiMo2API is a self-hosted reverse-proxy that converts Xiaomi MiMo AI Studio's web session into an OpenAI-compatible API. It does not proxy or touch the official Token Plan API (token-plan-cn.xiaomimimo.com).

Your issue is about the official MiMo Token Plan API endpoint itself being unreachable (connection refused / timeouts, with the 400 response even leaking an internal CloudML backend address). That's a server-side problem on Xiaomi's end and is unrelated to this project.

Please report it to the official channel instead — e.g. the MiMo AI Studio feedback/issue channels or their support. Closing this as off-topic.
