This article covers problems with the GoGuardian Teacher dashboard itself — the teacher-facing app at [teacher.goguardian.com](https://teacher.goguardian.com) — when it won't load or runs slowly. If instead a specific student shows as offline or disconnected, see [Student Offline](/products/teacher/student-offline). ## GoGuardian Teacher Won't Load Work through these steps in order; the first is the most common fix: 1. **Confirm you're signed in to the right place.** Go directly to [teacher.goguardian.com](https://teacher.goguardian.com) and confirm you're signed in with your school account. If you can't sign in at all, see [Fix GoGuardian Sign-In and Account Access Errors](/products/org-management/troubleshoot-login). 2. **Hard refresh the page,** then clear your browser cache and reload. 3. **Test in an incognito or private window.** This loads the page without your browser extensions. If Teacher works there, an extension is the likely cause — see below. 4. **Try another browser or device.** GoGuardian Teacher is supported in current versions of major browsers; an out-of-date browser can fail to load the dashboard. 5. **Confirm your network allows GoGuardian services.** A firewall or content filter may be blocking the dashboard. Have your network administrator confirm GoGuardian's back-end services are allowed, as listed under Cause 7 in [Student Offline](/products/teacher/student-offline#cause-7-firewall-is-blocking-goguardian-services). ## The Dashboard Is Slow or Unresponsive * **Reduce browser load.** Close unused tabs and other running applications, then restart the browser. Large class sessions with many student tiles use more memory. * **Restart the device.** Devices running for long stretches without a restart can develop performance problems. * **Update the browser.** Running the latest browser version resolves many rendering and performance issues. * **Check your connection.** A slow or unstable network delays the real-time updates the dashboard depends on. ## Rule Out a Browser or Extension Conflict Browser extensions — especially ad blockers such as AdBlock or uBlock — can block parts of GoGuardian Teacher and make it fail to load or behave unpredictably. 1. Reproduce the problem in an incognito or private window, which prevents most extensions from loading. 2. If that resolves it, remove, pause, or allowlist the conflicting extension. See [Disable AdBlock and uBlock](/products/teacher/disable-ad-blockers). 3. VPNs and other content-blocking or security extensions can have the same effect — disable them temporarily to test. ## Check for a Service Disruption If several teachers at your organization lose access at the same time, the cause is more likely a service disruption than any single device. Confirm with your IT administrator whether other staff are affected, then contact GoGuardian Support to check whether a known disruption is affecting your area. ## Collect Diagnostic Information for Support If the problem persists, speed up the support process by including: * The browser and version, and the operating system * A screenshot of the error or the loading state * The email addresses of affected teachers and roughly when the problem started * Whether the problem reproduces in incognito mode and on another device * Your Chrome policy export, if requested. See [Export Chrome Policy](/products/teacher/export-chrome-policy). Troubleshoot a student who shows as offline or disconnected. Stop ad-blocking extensions from interfering with Teacher. Export the Chrome policy support may request for diagnosis. Resolve sign-in errors that block access to Teacher.
