To fix this problem on your Windows 11/10, we recommend you follow our suggestions:
- Enable Flash for the website
- Clear browser cache
- Allow third-party cookies
- Disable Adblocker
1] Enable or Allow Flash for the website
This is the most crucial step you need to perform to resolve this issue. As this problem occurs only with Flash players on some sites, you must allow Flash in Google Chrome so the website can play the video. When you get this error, you need to click the ‘lock’ sign visible in the address bar. Here you see an option to allow Flash.
If you mistakenly blocked Flash on a website, you must follow these steps to enable Flash in Google Chrome.
Open Google Chrome and go to Settings > Advanced Settings. Under the Privacy and security section, find out the Content settings option. After that, click the Flash option. Alternatively, you can enter this in the address bar and hit the Enter button-
chrome://settings/content/Flash
Here you can find all the websites that cannot use Flash in your browser. Click the corresponding trash can icon to remove the website from the list.
I hope your problem is resolved. However, you can follow the next suggestion if you still face the same issue.
