Error message:
Cloud licensing not available in your network
Solution:
For the sake of the connection's safety and confidentiality, ETS needs a direct internet connection to the KNX servers without any proxy or firewall intercepting the communication in order the Cloud Licensing to work. Therefore, if you receive an error message like the one above please get in contact with your IT department to adjust the network policies (see here the addresses and the ports that ETS6 uses) or if this is not possible then you have to buy a dongle and use the dongle-based licensing.
