I am trying to configure a cellular modem Digi WR31 with OpenVPN, I was able to setup the server (CentOS 7) and i am able to conenct via windows client, OS cliente, as well as Android client. However when I try to establish a connection with the Digi modem the connection gets dropped.
first, the digi client connects but is not able to keep the connection up for more than 1.5 min average. ( the log only shows OVPN down)
OpenVPN log shows -
it looks to me that the same user, from the same digi modem tries to connect even when the connection already has been established."disconnected because user-specific properties prevent concurrent VPN connections by this user"
any help is appreciated.
