Yes Claude this is a duplicate, a deliberate duplicate because you did not fix the problem yet.

I found a way to fix the annoyance! Instead of starting with what work I need done, I politely say hi! This way I get either a reply or a 401. Somebody loses some tokens for the random hi, but oh well...

for the VS cod extension, the code claude login stopped working at all. It works well in the terminal mode, but in the extension the login just fails. I use /login and authenticate my Claude Max account, but then in the extension just nothing happens.

Cannot effectively work with code claude now, please help! this is started after claude v2 upgrade I think.

Hi everyone 👋 I encountered the same issue —
the Claude Code VS Code extension couldn’t log in or connect even though I have a Claude Pro subscription.

After some digging, I found the root cause and the full fix 👇

⚠️ Root Cause

The VS Code extension itself doesn’t handle authentication.
It relies entirely on the Claude CLI for login and token management.

If you haven’t installed or logged in via the CLI, the extension will fail with errors like:

❌ “Missing API key”
❌ “Unable to connect to Anthropic services”
❌ “401 Unauthorized”

✅ Solution: Link the VS Code extension to your Claude CLI login
1️⃣ Install Claude CLI
npm install -g @anthropic-ai/claude-code

2️⃣ Log in using your Claude Pro subscription
claude login --method=claudeai

💡 This will open a browser window for you to log in with your Claude.ai account.
After successful login, a file ~/.claude.json will be created to store your session.

3️⃣ Verify your login
claude whoami

You should see:

Using Claude.ai Subscription

✅ That means your Pro account is active and recognized.

4️⃣ Open VS Code again

Once the CLI is logged in, the VS Code extension will automatically detect your session —
no need to enter any API key or credentials manually.

🧰 Optional: If you use a local proxy

Add these environment variables to .vscode/settings.json:

{
"claude-code.environmentVariables": [
{ "name": "HTTP_PROXY", "value": "http://127.0.0.1:your" },
{ "name": "HTTPS_PROXY", "value": "http://127.0.0.1:your" }
]
}

Adjust the proxy address/port to match your setup.

🧠 Explanation

As of Claude Code v2.0.26,
the VS Code extension is just a front-end interface for the CLI.
All login, authentication, and API calls go through the CLI backend.

So the correct setup order is:

🪄 Install CLI → Log in (Pro) → Open VS Code

💬 In short

The extension doesn’t log in directly — it mirrors the CLI’s login session.
Make sure your CLI is logged in with Claude Pro, and the plugin will start working instantly.

API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. Please obtain a new token or refresh your existing token."},"request_id":"req_011CUda9zmnYUhb5VahYiCPU"} · Please run /login

How long? Is there anybody even working on this bug? Is it in attention to somebody that this is actually ANNOYING????

Happened again. Seriously, I will redirect the monthly 200$ to Codex if this keeps happening.

Took me a while and several tries to fix this but in the end it worked, here's what I did:

1. First you need to uninstall (not just disable) the Claude Code extension in VSCode and quit the app.

1. Reinstall Claude Code (you may want to back up before running these).

# remove all claude installs
brew uninstall claude-code claude
npm uninstall -g --force @anthropic-ai/claude-code
rm /opt/homebrew/bin/claude
rm ~/.local/bin/claude

# remove claude vscode extension
rm -rf ~/.vscode/extensions/*anthropic*

# clear settings
rm -rf ~/.*claude*

# clear passwords
security delete-generic-password -a "Claude Key"
security delete-generic-password -a $USER -s "Claude Code-credentials"

# reinstall claude
curl -fsSL https://claude.ai/install.sh | bash

# reinstall vscode extension via claude
claude /ide

1. Then reopen VSCode and if you type /cost into the Claude Code extension you should see your current plan.
