Vikings: War of Clans is under constant development: the game mechanics are becoming ever more complex and new graphical elements are constantly being added. The app needs a stable internet connection and up-to-date software in order to work correctly. Problems may be caused by third-party apps running on the device, or an outdated operating system or game version.

How does the data exchange work?

In response to any user action, the game sends a request to the server. If the device is working correctly, the internet connection is stable, and no third-party programs are creating obstacles, the data packet reaches the recipient in milliseconds. Then the information is processed, and after that, millions of other users receive it. If there are any problems accessing the global network, data packets from the player are transmitted with delays or do not reach their destination at all.


Let's look at possible reasons why the web version of Vikings: War of Clans may run incorrectly (Facebook and the portal).

1. Poor internet connection

Low connection speed, multiple connections through your access point, or other running programs may prevent the game from launching.

2. Browser cache contains erroneous data

As it runs, your browser saves various temporary files: pages, styles, images, site settings, and cookies. These are necessary to help web pages load faster and to automatically authorize you on websites. Over time, erroneous data can build up in the cache. When the cache is cleared, the temporary files are partially or completely deleted.

To clear the cache and other saved data in the browser, follow these steps:

1) Go to "Settings" ("Parameters") in your browser menu.

2) Open the additional settings (a subsection in the lower part of the screen). In the "Privacy and security" section ("Personal data"), select "Clear history" ("Clear browsing data"). You can also simply type into the setting search bar (the upper part of the screen) the name of the menu subsection you need.

3) Select which data should be deleted and for which period and hit "Delete data".

3. Some data in Vikings: War of Clans is outdated or contains an error

To clear your browser of outdated and/or incorrect game files, you need to do the following:

  1. Go to Settings in your browser menu.

  3. In the Permissions (Privileges) section choose "Cookies and site data" and then "All cookies and site data".
  4. In the "Search cookies" box at the top of the screen, type "krcdn".
  5. Hit "Remove all shown".
