For over a year, I have had two Mangos. One is set up as an OpenVPN server and the other other an OpenVPN client.
I did two things that made my connection really unstable and unusable.
First, I updated both units to the latest firmware. I even defaulted them.
I also added a Wireguard server. I know you can have a wireguard client and an open vpn client connected at the same time. Are you allowed to have an OpenVPN and a Wireguard server running at the same time but just only have one protocol in use at any one time or can I only have one server running at the same time?
It seems to work well for my initial test but then the next morning, I could connect with the wireguard client to the server but virtually no data would pass.
