Hi, for online subscriptions, outbound access to port 443 (HTTPS) has to be allowed on the host where the Workstation is running (more about this is available here https://kb.nomachine.com/AR11U01209). Rest assured that work is already being done to extend proxy support for outbound web connections, currently desktop client connections can be configured to connect through a proxy. Until then, we can provide license files that do not need to be checked online, what we call “offline” or “on-prem” licenses. You will need these also for machines that are not allowed to connect to the internet at all, Our support or sales teams will be happy to provide what you need in place of the license files you need 🙂
