Fix OpenClaw Browser Extension: Relay Not Working

"OpenClaw Browser Extension: Relay Not Working" means the browser extension cannot properly connect your active browser tab with OpenClaw.

The extension works like a bridge between your browser and OpenClaw. When the relay fails, OpenClaw may not be able to read the page, control the tab, click buttons, fill forms, or continue browser-based tasks.

This usually happens when:

• OpenClaw Gateway is not running
• The relay service is not reachable
• The browser tab is not attached
• The extension is disabled or missing permissions
• The wrong browser profile is being used
• VPN, firewall, or localhost settings are blocking the connection
• The browser session became stale after sleep, restart, or update

Why this matters: The browser extension needs the Gateway to communicate with OpenClaw. If the Gateway is down, stale, or not serving the local dashboard, the extension relay can fail.

Commands:

If restart does not work:

Then test:

What to check: Gateway is running, port 18789 is active, local dashboard opens, browser is not using an old/stale tab.

Why this happens: Sometimes the relay is available, but no active browser tab is attached. This is different from a Gateway failure.

Fix:

1. Open the website you want OpenClaw to control
2. Click the OpenClaw Browser Relay extension icon
3. Attach the current tab
4. Reload the page
5. Retry the browser action inside OpenClaw

Users often think "relay not working" means the full setup is broken, when the real issue is just that no tab is connected. A tiny missing click can stop the whole workflow.

Why this happens: The extension may be installed but not allowed to run on the current page.

Steps:

1. Open chrome://extensions
2. Find the OpenClaw Browser Relay extension
3. Make sure it is enabled
4. Open Details
5. Check site access
6. Allow access for the website you want to automate
7. Reload the tab
8. Click the extension icon again

Restricted pages: Browser extensions may not work on pages like chrome://settings, chrome://extensions, or chrome://flags. Avoid testing on browser-internal pages - they are not normal webpages.

Why this matters: OpenClaw may use a separate browser profile called openclaw. This profile is different from your normal Chrome profile. That means:

• Your personal Chrome tabs may not appear in OpenClaw
• Your logged-in sessions may not exist in the OpenClaw browser
• The extension may be attached to the wrong profile
• The agent may be using a different browser surface

OpenClaw docs explain that the openclaw profile is isolated from your personal browser profile, while a user profile can attach to a real signed-in Chrome session when needed.

Fix:

For logged-in websites, sign in manually inside the OpenClaw browser profile instead of giving credentials to the model. See our browser automation guide for more on profiles.

Tired of debugging local browser setup?

Ampere.sh runs OpenClaw with a managed browser environment. No relay issues, no extension permissions, no Gateway restarts. Just workflows that work.

Why this helps: This tells you whether the problem is the extension or OpenClaw browser control itself.

Why this happens: The extension may fail if local browser traffic cannot reach OpenClaw's local Gateway or relay service.

Check:

• Can you open http://127.0.0.1:18789?
• Is another app using port 18789?
• Is VPN blocking localhost traffic?
• Is firewall/security software blocking local connections?
• Are you trying to expose browser control publicly?

Commands:

Security warning: Do not expose browser control ports publicly. See our port change guide and use a node host or private network setup for remote browser control. Avoid public exposure of relay/control ports.

Why this matters: Linux users often hit browser automation problems because Chromium may be installed as a Snap package. Snap's AppArmor confinement can interfere with how OpenClaw spawns and monitors the browser process. See our Linux setup guide for full details.

Fix options:

• Use Google Chrome instead of Snap Chromium
• Use Brave or Edge if available
• Use a non-snap Chromium build
• Use attach-only mode when needed

Example config:

Why this happens: The relay can fail after laptop sleep, browser restart, Chrome update, Gateway restart, extension update, old tab/session state, or expired browser session.

Fix:

1. Close the target tab
2. Restart Gateway
3. Reopen the target website
4. Click the extension icon
5. Attach the tab again
6. Retry the workflow

If the Gateway works but the extension still fails, treat it as a stale browser/session problem before reinstalling everything.

Why this matters: Version mismatch can break browser relay behavior.

Then reload the extension: open chrome://extensions, turn Developer mode on, then click Reload on the extension.

Then restart:

If you are still on an older NPM-based version, see our NPM migration guide.

Likely cause: Extension disabled, site access blocked, wrong browser profile, no active tab attached.

Fix: Enable extension, allow site access, reattach current tab.

Likely cause: Gateway restarted, browser slept, Chrome updated, extension permission reset, stale tab state. Often related to general bot connectivity issues.

Fix: Restart Gateway, reload tab, reattach extension, confirm dashboard opens.

Likely cause: Browser cache, stale tab, wrong profile, extension state issue.

Fix: Open http://127.0.0.1:18789 directly, restart browser, reattach tab, reload extension.

Likely cause: Wrong browser profile, browser control not enabled, sandbox restrictions, host browser access not allowed.

Fix: Use openclaw browser tabs, use the openclaw profile, enable host browser control only when needed.

Likely cause: Snap Chromium, AppArmor confinement, sandbox/browser spawn issue.

Fix: Use Chrome, Brave, Edge, or non-snap Chromium. Use attach-only mode.

Local browser relay issues usually come from Gateway restarts, browser profiles, extension permissions, localhost access, stale tabs, and machine sleep. If you want to run OpenClaw workflows without managing local setup every time, managed hosting is the cleaner path.

Ampere.sh managed OpenClaw hosting helps you run OpenClaw without handling local setup, ports, Gateway uptime, Docker issues, or repeated environment debugging. You focus on workflows instead of babysitting relay connections.
