Troubleshoot Stream Alert Widgets in OBS, Streamlabs & Twitch

Stream alert widgets are the pop-ups that announce new followers, subs, tips, and raids on your Twitch channel. When they stop appearing or freeze mid-stream, it’s usually a connection, browser source, or overlay issue—not a broken stream. This guide walks you through the most common fixes in order, from the quickest check to the deeper settings, so you can get your alerts back on screen fast.

What You’ll Need

• Access to your streaming PC or laptop (the one running OBS or Streamlabs)
• Your Twitch account login (for reconnecting the alert widget)
• The dashboard URL or widget URL from Streamlabs or StreamElements (if you use either)
• 5–10 minutes of quiet time before your next stream

Step-by-Step

1. Check the obvious first: is the alert widget actually in your scene? In OBS Studio or Streamlabs Desktop, look at your Sources list. Find the source named something like “Alert Box,” “Streamlabs Alerts,” or “StreamElements Alerts.” If it’s missing, add it back: click the + under Sources, choose BrowserSource (OBS) or the Streamlabs widget option, and paste your widget URL (see step 3). If it’s there but greyed out, click the eye icon to make it visible.
2. Test the alert directly in the widget dashboard. Open your Streamlabs Dashboard (streamlabs.com/dashboard) or StreamElements (streamelements.com/dashboard). Find the Alert Box section. Click the “Test Alert” button for each type (follow, sub, tip, raid). If you see the test alert on your stream preview, the widget itself works—the issue is elsewhere. If not, the widget is broken or disconnected.
3. Verify the browser source URL is correct and current. In OBS, right-click the Alert Box source → Properties. The URL should look like https://streamlabs.com/widgets/alert-box/... or https://streamelements.com/overlay/.... If you copied it months ago, it may have changed. Go to your dashboard, copy the fresh widget URL, paste it into the browser source, and click OK. In Streamlabs Desktop, the widget is built-in—you don’t enter a URL, but you may need to re-add it from the “Widgets” tab.
4. Force a refresh of the browser source. Browser sources cache content. In OBS, right-click the Alert Box source → Refresh. In Streamlabs Desktop, click the widget in the Sources list, then click the refresh icon in the toolbar. If you’re using a custom browser source, also try pressing Ctrl+R while the source is selected (in OBS 28+).
5. Reconnect your Twitch account. Go to your Streamlabs or StreamElements dashboard → Settings → Connected Accounts. Disconnect Twitch, then reconnect. This re-establishes the API connection that tells the widget when a follow or sub happens. Wait 30 seconds after reconnecting, then test the alert again.
6. Check the alert widget’s volume and mute settings. Right-click the Alert Box source → Properties. Make sure “Mute” is unchecked. Also check the audio mixer in OBS—if the alert source’s volume is at 0%, you’ll see the visual but hear nothing. In Streamlabs, the widget has its own volume slider in the Widgets tab.
7. Look for conflicting browser sources or overlays. If you have multiple alert widgets (e.g., one for Streamlabs and one for StreamElements) or a scene with two alert sources, they can fight. Disable all but one, then test.
8. Update OBS/Streamlabs and your browser. Outdated software can break the embedded browser that powers widgets. Go to Help → Check for Updates in OBS, or the settings menu in Streamlabs. Also update your default browser—the widget uses the system’s Chromium engine.
9. Restart the streaming software completely. Close OBS or Streamlabs, wait 10 seconds, reopen. This clears any stuck processes. If you’re mid-stream, do this during a break—it will cut your stream for about 30 seconds.
10. Check Twitch’s service status. If alerts worked yesterday but not now, visit status.twitch.tv. If Twitch’s API is having issues, alerts will be delayed or not fire. In that case, wait it out—there’s nothing you can fix on your end.

Common Mistakes

• Using the wrong URL. Copying the dashboard URL instead of the widget/overlay URL. The widget URL ends with /alert-box or /overlay, not /dashboard.
• Multiple alert sources active. Having both Streamlabs and StreamElements alert boxes in the same scene—they overlap and only one shows.
• Forgetting to refresh after changing settings. You update the widget in the dashboard, but the browser source still holds the old version until you refresh it.
• Muting the source accidentally. Hitting the M key while the source is selected mutes it silently.
• Testing on the wrong scene. You test the alert while viewing a different scene in OBS, so you think it’s broken when it’s actually working fine.

Tips

• Set up a dedicated “Alerts Test” scene. Create a scene with just the alert widget, switch to it, and test. This isolates the widget from the rest of your overlay.
• Keep your widget URL in a text file. When you copy it from the dashboard, save it somewhere easy to find—you’ll need it again.
• Use the “Test Alert” button before every stream. A 10-second check saves you from discovering mid-stream that alerts are dead.
• Update OBS regularly. Browser source bugs are fixed in updates. Enable auto-updates if you can.
• If you use Streamlabs Desktop, prefer its built-in widgets. They’re more stable than custom browser sources because they’re integrated.

Troubleshooting

Alerts work in the dashboard test but not on stream: The browser source is likely pointing to an old URL. Re-copy the widget URL and paste it into the source properties. Also, make sure the source is actually visible in the scene you’re streaming (check the eye icon).

Alerts show but no sound: Check the source’s mute state in OBS, and the widget’s audio settings in the dashboard. Also, check your Windows volume mixer—OBS/Streamlabs might be muted there.

Alerts are delayed by 30+ seconds: This is usually a Twitch API delay or your internet connection. Test your connection speed. If it’s fine, wait a few minutes—delays often resolve themselves.

Only some alert types work (e.g., follows but not tips): Go to the widget dashboard and make sure each alert type is enabled and has a test button. If tips aren’t working, check that your Streamlabs account is connected to PayPal or Stripe.

The widget appears as a black box: The browser source failed to load. Refresh it (right-click → Refresh). If that fails, close and reopen the source properties, then click OK. If it’s still black, try a different widget URL or restart OBS.

Alerts worked on a previous stream but not now: Check if your Twitch account got disconnected (Step 5). Also, check if you changed scenes or moved sources between streams—the alert source might be in a scene you’re not using.

Frequently Asked Questions

Why do my alerts work in the dashboard but not in OBS?

Most likely the browser source URL is outdated or the source is hidden. Re-copy the widget URL from your dashboard and paste it into the source properties, then refresh.

Do I need to refresh the browser source every stream?

No, but it’s a good habit. Refreshing ensures the widget has the latest settings and reconnects if the connection dropped.

Can I use Streamlabs alerts with OBS Studio?

Yes. Copy the widget URL from Streamlabs and add it as a BrowserSource in OBS. It works exactly the same.

Why do my alerts show up on my preview but not on the actual stream?

This usually means the alert source is in a scene you’re not currently streaming, or the source is hidden (eye icon off) in the live scene. Check your scene list and source visibility.

What if I use StreamElements instead of Streamlabs?

The same steps apply. Use the StreamElements overlay URL in a browser source, and test via their dashboard. The troubleshooting is identical.

My alerts are working, but they’re covering my webcam. How do I move them?

In OBS, click the alert source and drag it to a new position, or use the transform controls (Ctrl+E to edit). In Streamlabs, use the Widgets tab to adjust the position and size.
