Have a somewhat similar issue to this one
In the gateway webpage, if you click Status>Gateway Network, you see a section for "Connections" and "Remote Gateways". Is there any way to remove gateways from the "Remote Gateways" list if there is no connection configured to them in the Gateway Network settings area? Did try to restart the gateway as that seemed to be the solution from the other post, but didn't have any effect.
Thanks in advance!
