Ive tried redoing the token and its still 429

429 isn’t an “auth key is bad” signal — it’s rate limiting / quota / overload. The reason it can work on one computer but not the other is usually one of these:

1. Different network / IP
   Office/VPN/VPS/datacenter egress IPs can get throttled much more aggressively than a home connection.
   Quick test: try the “broken” machine on a phone hotspot (no VPN). If it suddenly works, it’s the network/IP/proxy.

2. Different credentials are actually being used
   Claude Code has multiple auth paths (Claude Teams/Enterprise, Console API key, Bedrock/Vertex/etc) and it also supports apiKeyHelper in settings; settings can be managed at /etc/claude-code/ on Linux/WSL. So one machine may be using a different key/org than you think.

3. You’re hitting token/request limits on that machine because it’s doing more work
   Claude Code can generate a lot of requests (repo scanning, big context, parallel calls). That can trip tokens-per-minute limits even if “normal prompts” work elsewhere.

If you paste the exact 429 error text (redact the key; keep the message + any request id), I can tell which bucket it is. Also: what environment is failing (OS, home vs office/VPN, local vs VPS)?

If you want a fast self-check: from the failing machine run a single tiny API call (using your env var key) and see if it still 429s immediately — that distinguishes “API/account limit” vs “Claude Code usage pattern / concurrency / repo size”.

HTTP 429: rate_limit_error: This request would exceed your account's rate limit. Please try again later. (request_id: req_011CY9VqAPWX9iMqDzVUSyta)

That specific message means Claude Code did authenticate, but Anthropic rejected the call because it would exceed your org/account API rate limits (TPM/RPM / spend-tier limits). It’s not a “bad key” error.

Why it can work on one computer but not the other usually comes down to one of these:

1. They’re not actually using the same auth/account

• One machine might be using a different API key / different Anthropic org, or even a different auth method (Claude Teams/Enterprise vs Console API key).
• Easiest check: confirm the two machines are using the same key (compare last 4 chars locally; don’t paste it here).

2. The failing machine is sending a much bigger request

• Big repo context / lots of files / multiple concurrent requests can exceed your per‑minute token budget even if “normal prompts” work elsewhere.
• Quick test: run Claude Code in an empty/small folder and ask something tiny.
• If that works → it’s repo size / context / concurrency.
• If that still 429s immediately → it’s truly your account/org limit.

3. Something else is burning the limit in the background

• Another Claude Code session, CI job, editor plugin, etc. using the same key can push you over.
