What's Wrong?

I'm using a machine sharing with other people under the same user account on linux. The machine is located in U.S..

After login and run any prompt, I got

hello                                                                                                                                                  
  ⎿  API Error: 401 {"error":{"message":"没有有效的订阅计划","type":"authentication_error"},"type":"error"} · Please run /login

I've tried using the solution from previous issues, e.g. https://github.com/anthropics/claude-code/issues/5893#issuecomment-3193488709, but neither work for me.

I'm a Max plan user. My claude code works perfectly as I'm in China using VPN connecting to either Hong Kong or U.S. But it surprise me not working for machines exactly located in U.S.

Other interesting point is that the error message is in Chinese (没有有效的订阅计划, means "No valid subscription plan.") on that U.S. machine. Is claude showing language based on its picture for the user? Does that means that claude is collecting user data and treat user seperately)? :)

What Should Happen?

Should work on U.S. machine as it has already works on my Chinese machine with VPN.

However, I'm using "1. Claude account with subscription · Pro, Max, Team, or Enterprise", not "2. Anthropic Console account · API usage billing" for billing.

Then exit:

/exit

1. re-enter claude, prompt anything, and got above error
