Its possible related to a missing add on such as Adobe Flash Player not enabled. Can you determine if the site works in Microsoft Internet Explorer or not?
Press Windows key + R
Type: iexplore
Hit Enter
If you happen to be using Edge and you get and error when you load a site requiring Flash, itâ's possible it's just disabled.
To change that, open the More actions menu in the top right corner of the Edge browser, scroll down, click the View advanced settings menu then toggle on Adobe Flash Player. Refresh the web page or close Microsoft Edge then open it again. In rare cases, you might need to restart your computer
If theres no overt signs on the page that Flash needs to be enabled, but you still sense that there is some missing content, then itâ€:tm:s possible that Flash content isnâ€:tm:t loading. This may be by design; as a security measure, Microsoft is limiting the use of Flash where ever it can. So, if you are greeted by a web page with only a puzzle symbol, donâ€:tm:t be puzzled. Instead, look in the address bar, then click the puzzle icon. From here, you can choose whether you want to allow the website you are viewing to always run Adobe Flash or Allow it once.
Update Adobe Flash Player in Windows 10
Since Microsoft bundled Adobe Flash in Windows, you also get Adobe Flash updates via Windows Update. So, if you have tried all the above and Flash still refuses to load in Microsoft Edge, you likely need to install an update.
Open Start > Settings > Update & security > Windows Update > Check for updates. Download and install the latest update for Flash if it's available.
Sometimes even Windows Update might prove problematic when installing updates for Flash Player updates. What you can do is download the update for Flash Player manually from the Microsoft Update Catalog. We showed you how to do that in our previous article on how to install Windows updates manually.

If you still continue to experience problems viewing Flash content, then you might want to try to repair or reset Microsoft Edge.

What About Other Web Browsers?
Windows 10 bundles Adobe Flash for use with the Edge browser. If you use Google Chrome, Mozilla Firefox or other web browsers, you will need to either enable or download then install Adobe Flash manually. In Chrome, when you visit a website that requires Flash, click the Secure menu in the left of the address bar then click Site settings.
Scroll down, click in the list box for Flash then select Allow.
If Flash still does not work, you likely need to update it. In the Chrome address bar, type chrome://components then hit Enter. Scroll down then click Check for the update under Flash Player.
Mozilla Firefox
In Firefox, first, check if Flash is enabled. Click the Open menu , then Add-ons, Plugins then click on Preferences for Shockwave Flash. Click on the Choose Change when this add-on runs list box then choose Always Activate.
Updating Flash on Firefox requires users to visit Adobeâ€:tm:s download page where they can download and install the latest versions for their respective web browser.
