If your system time is, for example, set to April, 1st, , an SSL certificate from will be rejected and the connection will fail. Very often an operating system just made a wrong turn here or there, so before you go through all the hassles of searching for a reason, please deinstall CyberGhost VPN completely and re-install it.

This already solves many problems without exactly knowing why they appeared in the first place. Windows 7 update blocks network traffic: There is an optional update for Windows 7 which, if installed, blocks network traffic. Only solution: Deinstall the update.

Malwarebytes 2 disables CyberGhost: If CyberGhost and Malwarebytes 2 are both installed at the same time on the same PC, there is a fair chance that certain incompatibility problems can result in failed connections.

We are constantly working on adapting CyberGhost each time we found out about a software product that causes this behavior.

Please install the latest beta version of CyberGhost, when encountering such a problem. It might resolve it. You can let CyberGhost download the latest beta automatically by activating the respective option in the general program settings.

Driver Problems Third party driver: If your system contains other VPN software along with CyberGhost, the adapter used by them might interfere with each other so that the corresponding applications can’t connect properly with their respective network adapter. Contact support to get informed of how to repair the driver. Self help for experts: Network adapter is not activated: Certain programs deactivate the virtual network board, which is generated when installing CyberGhost VPN.

Server Problems Server Downtimes: Please check, if your problem also persists with different servers in different countries. If you have connection problems with a single server or country, it’s quite likely a temporary problem or downtime, e. If the problem persists on all servers, please also check your firewall and anti virus settings see below. CyberGhost gets blocked: Another reason that keeps CyberGhost from connecting might be the blockage of the CyberGhost URL, especially but not solely in countries with restrictive governments.

Sometimes only deactivating a firewall is not enough and you better deinstall it temporary or at least restart the computer after deactivating. If you can access the CyberGhost network after deactivating that firewall, try to fix the problem by adjusting the firewall settings, so you can use CyberGhost VPN without deactivating your firewall protection.

Basically, this solution does not endanger your system, because it’s just the CyberGhost VPN server, that’s communicating with this adapter the server and the client are authenticated based on certificates , and the CyberGhost-VPN server has its own Firewall functions. In such cases, you can remedy the situation by activating the ports ”, ”, ”, ”, and ”. The afferent functions are available in the firewall settings, respectively, in the router settings.

CyberGhost and Kaspersky: Otherwise you will not be able to establish a connection and will receive an error message, while trying to connect.
