Frequently Asked Questions

1. What browsers or devices work best with CLE Nation?

CLE Nation works best on the latest versions of Google Chrome, Safari, Microsoft Edge, or Firefox. Our platform is fully compatible with desktop, laptop, tablet, and mobile devices.

For the best viewing and course experience, we recommend:

• Using a stable internet connection (Wi-Fi or wired preferred).

• Enabling cookies and JavaScript in your browser.

• Keeping your browser updated to the most recent version for security and performance.

If you experience any playback or access issues, try refreshing your browser, clearing your cache, or switching to another supported browser. Our support team is always available at support@clenation.com to help troubleshoot any technical issues.

2. How do I fix audio or video playback issues?

If you’re having trouble watching a course on CLE Nation, try the following steps — many issues can be resolved quickly. Because we use Vimeo to deliver video content, these tips align with Vimeo’s guidance for smoother playback.

Quick-start checks

1. Make sure you have a stable internet connection. Vimeo recommends a minimum of about 500 kbps for even the lowest playback quality. Vimeo Help Center+1

2. Ensure you’re using an up-to-date browser version (Chrome, Firefox, Microsoft Edge or Safari). Out-of-date browsers often have trouble decoding modern video streams. Repairit+1

3. If the audio is missing or the video is frozen, try refreshing the page or closing and reopening the browser. Many issues are temporary hiccups.

4. Clear your browser cache and cookies, then try again. Cached data can become corrupt and interfere with playback. Vimeo Help Center+1

More advanced troubleshooting

• If the video keeps buffering, switch the playback quality to “Auto” (from the gear icon in the Vimeo player). This allows Vimeo to choose a lower resolution if your connection fluctuates. Vimeo Help Center

• If your audio is out of sync with the video, check if you have many browser tabs/applications open. High system load can cause frame drops and sync issues. Vimeo Help Center

• If you’re embedding or viewing from a website with strict privacy or embed-settings, make sure the referrer policy isn’t blocking Vimeo from verifying domain permissions (common if you see a “privacy settings” error). Vimeo Help Center

• On Chrome (or other Chromium browsers), if you’re using any extensions or ad-blockers, disable them temporarily — some can interfere with video playback. Vimeo recommends testing in an incognito/private window to bypass extensions. Vimeo Help Center+1

• If you’re on a mobile device or tablet and experiencing playback issues, try closing other apps, restarting your device, or switching from WiFi to a mobile hotspot (or vice-versa) just to isolate the connection.
