WebHarvy registration involves online activation. So, internet connection is required for successful registration/unlock of trial version of WebHarvy using the license key file. Each WebHarvy license (except site license) has a fixed number of activations. Activations beyond this limit will not be allowed.
Please try the following in case you are unable to perform activation:
1. Please check if your firewall/antivirus is blocking WebHarvy. WebHarvy's configuration browser and miner will work without firewall/antivirus exceptions (since they are browsers), but activation will fail if the connection request to our license server is blocked. So, in case online activation fails please try again after adding rules/exceptions in your firewall/antivirus to allow outgoing connections from WebHarvy.
2. Sometimes your internet provider may be blocking the connection to our license server. In such cases, connecting to internet using another network and then performing activation will work. For example, you may connect to another Wi-Fi network or your mobile hotspot and then perform activation.
3. You may also try after changing the DNS server addresses which your computer uses. Try to unlock after changing the DNS server addresses to 8.8.8.8 / 8.8.8.4 (Google Public DNS), or to 1.1.1.1. You may refer this article to know how to change DNS settings in Windows.
