To prevent stolen user accounts from being abused, some online casinos (and possibly some other sites) perform origin checks to the connections. For example, if a user connects from Sweden but has specified himself as French when he originally registered to the casino, the online casino may consider this suspicious and blocks the user account.
As F-Secure Freedome VPN can be used to route the network traffic through any of the virtual locations in multiple countries, these kinds of origin checks may block you from accessing the site. To overcome this problem, we advise you to use the virtual location, i.e. the country that you entered in your user account when you registered to the casino.
