Fix OpenClaw Disconnected 1008: Gateway Token Error

You open your terminal, start OpenClaw, and instead of your AI assistant waking up, you get the OpenClaw disconnected 1008 error:

disconnected from gateway (1008): unauthorized: gateway token missing

Or its cousin:

disconnected from gateway (1008): unauthorized: token mismatch

This is the single most common error in the OpenClaw ecosystem. If you search GitHub issues, Reddit, or any OpenClaw community, you'll find hundreds of threads about this exact message.

The good news: it's almost always fixable in under 2 minutes. Here's what's happening and how to fix it.

What Does the 1008 Error Mean?

The 1008 is a WebSocket close code that means policy violation — in OpenClaw's case, it means the gateway rejected your connection because the authentication token is missing, expired, or doesn't match.

OpenClaw has two main components that need to talk to each other:

1. The Gateway — handles incoming messages from Telegram, Discord, etc.
2. The Agent — the AI brain that processes messages and takes actions

These two components authenticate with each other using a shared token. If the token doesn't match on both sides, you get the 1008 error.

Root Cause 1: No Token Generated

Symptom: Fresh install, never worked.

After installation, OpenClaw needs to generate a gateway token. If you skipped the onboarding wizard or used non-interactive mode, the token may never have been created.

Fix:

openclaw doctor --generate-gateway-token
openclaw gateway restart

This generates a fresh token and writes it to both the gateway config and the agent config.

Verify:

openclaw doctor

Look for a green checkmark next to "Gateway token" in the output.

Root Cause 2: Token Mismatch After Config Edit

Symptom: Was working, broke after editing openclaw.json.

The gateway token lives in two places in your config:

{
  "gateway": {
    "auth": {
      "token": "your-token-here"
    }
  }
}

In older OpenClaw versions (pre-2026.2), it was at gateway.token instead of gateway.auth.token. If you copied a config from an old tutorial or mixed old and new settings, the agent and gateway end up looking for the token in different locations.

Fix:

Check your OpenClaw version and use the correct config path:

Or just let OpenClaw fix it:

openclaw doctor --fix
openclaw gateway restart

Root Cause 3: Docker Rebuild Generated a New Token

Symptom: Was working, broke after docker-compose up --build or docker build.

This is the #1 trap for Docker users.

When you rebuild your OpenClaw container, the build process runs openclaw onboard --non-interactive, which generates a new random token inside the container. But your gateway (or the config mounted via volume) still has the old token. Instant mismatch.

Fix (Option A) — Pin the token in docker-compose.yml:

services:
  openclaw:
    environment:
      - OPENCLAW_GATEWAY_AUTH_TOKEN=my-fixed-token-here

This way, rebuilds always use the same token.

Fix (Option B) — Regenerate after rebuild:

docker-compose up --build -d
docker exec -it openclaw openclaw doctor --generate-gateway-token
docker restart openclaw

Fix (Option C) — Mount a persistent config volume:

volumes:
  - ./data:/app/data

This preserves your openclaw.json (including the token) across rebuilds.

We recommend Option A + Option C together — pin the token AND persist your config. This makes your setup rebuild-proof.

Root Cause 4: Upgrade Changed the Token Format

Symptom: Broke after running openclaw update or pulling a new Docker image.

Some OpenClaw upgrades in 2026 changed the token generation algorithm or config schema. Running openclaw update without openclaw doctor afterward can leave you with a stale token.

Fix:

After every OpenClaw update, run:

openclaw doctor --fix
openclaw gateway restart

Make this a habit. Better yet, add it to your update script:

#!/bin/bash
openclaw update
openclaw doctor --fix
openclaw gateway restart
echo "Update complete"

Frequently Asked Questions

What does OpenClaw error code 1008 mean?

Error 1008 is a WebSocket close code meaning "policy violation." In OpenClaw, it means the gateway rejected your agent's connection because the authentication token is missing, invalid, or doesn't match between the agent and gateway components.

How do I find my OpenClaw gateway token?

Run openclaw doctor to check if a token exists. The token is stored in openclaw.json at gateway.auth.token (OpenClaw 2026.2+) or gateway.token (older versions). You can also check with cat ~/.openclaw/openclaw.json | grep token.

Why does my OpenClaw gateway token change after Docker rebuild?

Docker rebuilds run openclaw onboard --non-interactive, which generates a new random token inside the container. If your gateway config is not mounted as a persistent volume, the old token is lost. Fix this by pinning the token as an environment variable or mounting a persistent data volume.

Is "openclaw gateway token missing" the same as "token mismatch"?

Not exactly. "Token missing" means no token was generated at all — common on fresh installs. "Token mismatch" means both sides have a token but they don't match — common after Docker rebuilds or config edits. Both produce the same 1008 error but have different fixes.
