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 need to allow Flash in Google Chrome so that 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 have mistakenly blocked Flash on a website, you need to 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-
