To properly activate your license online, you need an Internet connection.
If this does not work, please check the following:
– Are you connected to the Internet?
– Check your firewall settings so it does not block the license activation.
– Do you use a proxy? Please check the following article: ‘Can I activate through a proxy?’

If you are not allowed to activate your license online, please consider offline activation (only for node-locked licenses)- please check:
