Fixing OpenClaw Gateway Token Mismatch WebSocket Errors

The Token Mismatch Error

You’ve been running OpenClaw happily on your Azure VM, configs changed, gateway restarted multiple times — then suddenly you see this in the logs:

2026-02-26T00:00:15.484Z [ws] unauthorized conn=f5c5408b-6704-4451-8e6d-858fb7052533
  remote=127.0.0.1 client=gateway-client backend vdev reason=token_mismatch

Followed immediately by:

2026-02-26T00:00:15.487+00:00 gateway connect failed:
  Error: unauthorized: gateway token mismatch (provide gateway auth token)

And the connection is torn down:

2026-02-26T00:00:15.505Z [ws] closed before connect
  conn=f5c5408b-6704-4451-8e6d-858fb7052533 remote=127.0.0.1
  fwd=n/a origin=n/a host=127.0.0.1:18789 ua=n/a
  code=1008 reason=unauthorized: gateway token mismatch (provide gateway auth token)

This is a WebSocket-level authentication failure — the client tried to connect to the gateway but presented a stale or wrong auth token.

How Gateway Tokens Work

OpenClaw uses a token-based authentication system for all WebSocket connections to the gateway. When the gateway starts, it reads (or generates) an auth token stored in its state directory:

~/.openclaw/credentials/

Every client connecting to ws://0.0.0.0:18789 must present this token. That includes:

• The CLI (openclaw-cli) when executing commands via the gateway
• The Control UI dashboard
• Paired devices (phones, other machines)
• Internal gateway-client connections (backend services)

Why Token Mismatch Occurs

The most common scenarios:

1. Token Regenerated After Restart

If the gateway regenerates its token on startup (due to missing or corrupted credential files), all previously-connected clients still hold the old token.

2. Multiple Config/Restart Cycles

In a session like the one shown in the terminal output where you run many config set commands followed by docker compose restart, the gateway may cycle through multiple restarts. If a background client was connected to a previous instance, it reconnects with an outdated token:

# Rapid config changes — each followed by restart
docker compose run --rm openclaw-cli config set agents.defaults.memorySearch.provider local
docker compose run --rm openclaw-cli config set agents.defaults.memorySearch.model all-MiniLM-L6-v2
# ... 7 more config sets ...
docker compose restart openclaw-gateway

3. Dev vs Production Profile Mismatch

Running openclaw --dev gateway isolates state under ~/.openclaw-dev/, generating a separate token. If you then connect a client configured for the production profile, it’s a guaranteed mismatch:

# Dev mode uses isolated state
openclaw --dev gateway     # token in ~/.openclaw-dev/credentials/
openclaw gateway           #  token in ~/.openclaw/credentials/

4. Docker Volume Token Persistence

If you rebuild the Docker image or recreate volumes, the in-container token at /home/node/.openclaw/credentials/ may differ from what paired devices remember:

# This preserves credentials:
docker compose restart openclaw-gateway

# This may regenerate credentials:
docker compose down && docker compose up -d

Diagnosing the Problem

Step 1: Check the Gateway Logs

Filter for authentication-related events:

docker logs --tail=100 openclaw-openclaw-gateway-1 | \
  grep -i "unauthorized\|token_mismatch\|closed before connect"

Look for the reason=token_mismatch field — it confirms the token itself is wrong, not an origin or header issue.

Step 2: Inspect the Connection Details

The log line contains useful metadata:

Step 3: Check Current Token

From inside the container:

docker exec -it openclaw-openclaw-gateway-1 sh -lc \
  'ls -la /home/node/.openclaw/credentials/'

Or via CLI:

docker compose run --rm openclaw-cli config get gateway.auth

Fixing the Mismatch

Option 1: Restart the Client

If the gateway token is correct and the client is stale, simply restart whatever client was trying to connect. For the internal gateway-client backend vdev:

docker compose restart

Option 2: Re-pair Devices

If paired devices (phone, laptop) can’t connect:

# List all paired devices
docker compose run --rm openclaw-cli devices list

# Generate a new pairing code
docker compose run --rm openclaw-cli qr

Scan the new QR code from your device to re-authenticate with the current gateway token.

Option 3: Force Token Reset

If the token state is corrupted, you can force the gateway to regenerate:

# Stop the gateway
docker compose down openclaw-gateway

# Remove the credentials directory (it will be regenerated)
rm -rf ~/.openclaw/credentials/

# Restart — a new token is generated
docker compose up -d openclaw-gateway

Warning: This invalidates ALL existing connections and paired devices. Every client must re-authenticate.

Option 4: Copy Token to Client

If you’re connecting from another machine or a dev profile, copy the token manually:

# Read the current gateway token
docker compose run --rm openclaw-cli config get gateway.auth.token

# Set it on the client machine
openclaw config set gateway.auth.token <TOKEN_VALUE>

Preventing Future Mismatches

1. Batch Config Changes

Instead of running multiple config set + restart cycles, batch your changes and restart once:

# All changes, then ONE restart
docker compose run --rm openclaw-cli config set agents.defaults.memorySearch.provider local
docker compose run --rm openclaw-cli config set agents.defaults.memorySearch.model all-MiniLM-L6-v2
docker compose run --rm openclaw-cli config set agents.defaults.memorySearch.cache.enabled true
# ... more config sets ...

# Single restart at the end
docker compose restart openclaw-gateway

Many settings are hot-reloaded anyway — check the gateway logs for [reload] config change applied messages before restarting unnecessarily.

2. Use restart Instead of down/up

docker compose restart preserves the container’s state directory. Avoid docker compose down unless you intend to recreate containers:

# Preserves token:
docker compose restart openclaw-gateway

# May generate new token:
docker compose down && docker compose up -d

3. Persist Credentials in Named Volumes

Ensure your docker-compose.yml maps a named or bind-mount volume for the .openclaw directory:

services:
  openclaw-gateway:
    volumes:
      - /home/azureuser/.openclaw:/home/node/.openclaw

This ensures credentials survive container recreation.

4. Monitor WebSocket Health

Add a health check that watches for token errors:

#!/bin/bash
# check-ws-auth.sh
ERROR_COUNT=$(docker logs --tail=50 openclaw-openclaw-gateway-1 2>&1 | \
  grep -c "token_mismatch")

if [ "$ERROR_COUNT" -gt 0 ]; then
  echo "WARNING: $ERROR_COUNT token mismatch errors in recent logs"
fi

WebSocket Close Codes Reference

The code=1008 in our error maps to a policy violation — the gateway rejected the connection because the authentication didn’t pass.
