Hello OBSeismo, and welcome back to the community!
We have other Shakers that use their instruments within a VPN, so when you changed to NordVPN, some settings must be adjusted for complete data transmission. If you follow Philip’s advice, you should be able to restore full connection between your Shake and our servers.
If not, please download the logs from the Shake itself and post them here, so that I can take a more detailed look into the situation. If yo need instructions on how to do so, you can find them at this page: Please read before posting!
Thank you.
