You need to update your cloud connector because you are running an older version that does not support the new features on the cloud. **Please note that the cloud connector doesn't update automatically anymore, since with version 7.0.0, .Net-version 4.6.2 is used.**
Download the new cloud connector from our helpdesk and save it on the server you want to install the cloud connector
Make sure that no user is logged in when installing the new cloud connector since it might create new UDT/UDF
Navigate to the path where you've saved the cloud connector, right click on it and choose Run as administrator
Follow the installation wizard. After finishing with the installation, the cloud connector should automatically start and synchronize again.
