How to Fix the OpenClaw Gateway Token Login Error

If you have hit a Gateway token login error, the first instinct is usually to re-check your model API key. That is almost never the actual problem. The Gateway token is a separate thing entirely, and understanding what it does makes the fix obvious in most cases.

What the Gateway token actually authenticates

Your ANTHROPIC_API_KEY (or whichever provider key you use) authenticates OpenClaw to the model. The Gateway token authenticates a client to your running OpenClaw instance — the Control UI, a mobile app, a CLI session, anything that connects to the Gateway rather than being the Gateway itself. When a client presents a token the Gateway does not recognise as current, you get a login error, and the model provider is never involved.

That distinction matters because it tells you where to look: not your .env provider keys, but the session/auth state the Gateway itself is holding — which, since a recent stable release, lives in SQLite rather than scattered config files.

The most common cause

The token the Gateway has on record and the token your client is presenting have drifted apart. This happens in a few predictable ways:

You upgraded OpenClaw across the release that moved auth profiles into SQLite, and an older client still has a token issued against the previous store.
You regenerated credentials (rotating the token, or reinstalling the Gateway) without restarting or re-authenticating the clients that were already connected.
A client cached a token from a session that the Gateway has since invalidated — a laptop that slept for days, or a mobile app that was not open during a restart.

In all three cases, the fix is the same shape: get the Gateway's current token state and the client's presented token back in sync.

Fixing it, step by step

Confirm which mode you're running. Direct mode and node mode handle Gateway sessions differently, and node mode has had specific session-handling bugs — worth ruling in or out before you touch anything else.
Run the doctor preflight. It exists precisely for this class of drift: it checks your auth store, migrates legacy config automatically, and flags a token mismatch rather than leaving you to guess.
Regenerate the Gateway token and restart every connected client. Don't just restart the Gateway — a client holding a stale token will keep presenting it until it is forced to re-authenticate.
Check the clock on both machines. Session and lease validation is time-bounded, and recent releases specifically tightened validation around lease timestamps. A few minutes of drift between a client and the Gateway host is enough to produce what looks identical to a bad token.
Check permissions on the auth store. Since auth profiles moved into SQLite, a Gateway process that cannot write to its own database will fail to persist a refreshed token — which reads exactly like a login error on the next attempt.

Work through these in order. Most Gateway token errors resolve at step 2 or step 3.

If you're on an older version

If you have not upgraded in a while, update before doing anything else. The exact failure mode of "a healthy direct Gateway session gets silently abandoned in favour of a reconnect" was a known bug on macOS in node mode, fixed in a recent stable release — see our release highlights for the specifics. If you are troubleshooting this on an older version, you may be chasing a bug that has already been fixed rather than a configuration problem in your setup.

When it's not actually a token problem

If the steps above don't resolve it, make sure you are diagnosing the right layer. A model provider error (invalid API key, rate limit, expired OAuth grant for a skill) can produce a failure that looks superficially similar in the logs but has nothing to do with Gateway sessions at all. Check the actual error source before assuming it's the Gateway — the fix for a provider credential issue is entirely different from the fix for a session token mismatch.

The pattern worth remembering

Gateway token errors are a sync problem, not a security problem or a broken install. Once you separate "what authenticates to the model" from "what authenticates a client to my Gateway," the troubleshooting gets fast: confirm the mode, run doctor preflight, resync the token, restart the clients, and check the clock. If you are still stuck after working through this, or you'd rather not debug Gateway sessions during a production outage, talk to us — this is exactly the kind of setup issue we resolve for clients as part of ongoing OpenClaw support.
