해결법

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)? :)
