Error M3U8

What causes the “error M3U8”?

We examined the problem after receiving several user reports and came up with a set of repair strategies that helped resolve the error. What's more, We investigated the reason this error was being triggered and found three of the most common ones listed below.

• Firewall: the first type of error that the message »Cross-domain access denied» is shown is because it is blocked by a proxy or a firewall. A certain video may be blocked in your country or, for some reason, the firewall considers it dangerous, so it may not load and show this error.

• Cookies: It implies the second type of error and displays the message “There are no levels to play”. This error appears when you have denied access to third-party data and cookies in your privacy settings.

Solution 3: use incognito mode

All major browsers have a private mode / incognito in which the browser starts without extensions and caches the data. To rule out if any of the extensions or saved or cached data is creating the problem, start the browser in incognito mode / private. By way of illustration, we will use the Chrome browser.

1. Chromium launch.

2. Click on 3 points and then click New Incognito Window. Open Chrome's incognito mode

3. Now visit the web page where you had trouble playing the video and see if you can play it smoothly.

4. If you were able to play the video in private mode / incognito, clear cache or disable potentially problematic extensions. Extensions like Adblock are known to create this problem. In Chrome, it is known that the browser extension “HTTPS Everywhere” is the main cause of this problem.
