[BUG] OAuth error: Request failed with status code 403

同样的问题，兄弟你解决了么

同样的问题

问题解决了，目前可以正常运行，以下是解决方案：
1.不要太过于相信vpn全局，git bash或者cmd、终端里面用curl ifconfig.me出去看看自己公网ip
2.https://tool.hiofd.com/ip/这里查询ip地址，claude限制国家挺多的，我这边可以发现自己挂全局vpn仍然是中国的ip
3.如果发现自己是限制国家ip，那么用proxy设置http代理端口，再次curl ifconfig.me出去发现ip不是限制国家ip即可。
p.s.如果问题解决了麻烦兄弟们来我csdn点一下关注，我后续还会在csdn上面发详细教程

Issue Resolution Summary:
Do not rely solely on VPN global mode.
Use curl ifconfig.me in Git Bash, CMD, or terminal to verify your actual public IP address.
Check your IP location via https://tool.hiofd.com/ip/.
Claude enforces strict geolocation restrictions. In some cases, even with a global VPN enabled, the outbound IP may still appear to be from a restricted country (e.g., China).
If your IP is from a restricted region, configure your system or application to use an HTTP proxy.
After setting the proxy, re-run curl ifconfig.me to confirm that your IP now originates from an allowed country.
P.S. If the issue has been resolved, kindly consider following my CSDN blog; I will continue to post detailed tutorials there.

依据以上贡献者的启发，我详细阐述我的解决方法，以解决在cursor中使用Claude code vscode插件出现的网络问题（以mac系统为例）：
编辑 Shell 配置文件（推荐）

确定您使用的 Shell

bash echo $SHELL

编辑对应的配置文件

如果是 zsh（macOS 默认）：

bash nano ~/.zshrc

如果是 bash：

bash nano ~/.bashrc

在文件末尾添加以下内容

bash export https_proxy=http://127.0.0.1:7890
export http_proxy=http://127.0.0.1:7890
export all_proxy=socks5://127.0.0.1:7890

# 可选：设置不走代理的地址
export no_proxy=localhost,127.0.0.1

保存并使配置生效

bash source ~/.zshrc # 或 source ~/.bashrc

现在的问题是当我成功登录Claude.ai Pro 账户后，浏览器是可以正常使用claude ai的，但通过claude code的cli方式login时，粘贴授权码后，一直报错：OAuth error: Request failed with status code 403。另外，IP已经确定是没问题的，也没有指定环境变量

解决了吗？我也是，不过有过一次成功登录，是在windows下，登录完后，电脑重启，以及在安装目录下进行了一次/init，windows下安装的claude code 顺利执行完/init 了，之后也可正常对话

hey guys, thank you for the solution! On Astrill i could some times make claude code work, some times not. so when it worked, i asked it to make a VPN from scratch, that when activated, run script to apply proxt to terminal, and ever since it has been running smooth - it also helps when i try to use gemini etc. I wrote a bit about it here https://blaris.com/blarisvpn - if there is any interest, i could publish it on github, no problem.

感谢解决了，让终端也能访问到vpn就行了

确实，通过这个能查询到正确的公网IP地址 https://tool.hiofd.com/ip/

IP正常的，但是登录时候还是提示“API Error: 403 用户没有有效的claudecode订阅 · Please run /login”，已经订阅了pro了，不知道什么情况～我是完全技术小白，有没有大佬可以给看看，感谢

更新：已解决，梯子不太行，换了代理，再使用上面解决方案可以了

Clash for Windows 默认使用的是 HTTP/SOCKS5 代理，它的工作方式是设置系统代理（即修改 Windows 的"Internet 选项"里的代理设置）。但问题是：CMD 里的 curl 默认不走系统代理
方法一：手动设置环境变量（临时）
在 CMD 里执行：
bashset http_proxy=http://127.0.0.1:7890
set https_proxy=http://127.0.0.1:7890
然后再 curl ifconfig.me 就会走代理了。端口号 7890 以你 Clash 实际配置为准。
方法二：开启 Clash 的 TUN 模式（真全局）
在 Clash for Windows 里：

进入 General 页面
打开 TUN Mode（或者叫 Service Mode，可能需要先安装服务）

TUN 模式会创建一个虚拟网卡，在网络层劫持所有流量，这才是真正的全局代理，所有应用包括 CMD、游戏、各种命令行工具都会走代理。
方法三：PowerShell 用户
powershell$env:http_proxy="http://127.0.0.1:7890"
$env:https_proxy="http://127.0.0.1:7890"

是的，已经解决了；之前的解决方案是没有问题的，主要是梯子的问题，换了代理，也打开了TUN Mode现在可以使用了。
