OPenVPN client with truenas core ?

[profwalken]

Hi,
I'm trying to connect to a TN CORE 13.0-U6.1 via a OpenVPN client and I get disconnected in a loop of few seconds.
On NAS side OpenVPN server is set and seems to work properly as another computer reach it successfully.

What I did:
install client on Windows 11 Pro PC
imported OVPN profile
try to connect, access is ok but a couple of seconds after it's disconnected and loop like this .

I tried differents client --> behave the same.
As i'm not expert in VPN and TN core services, any advices is greatly appreciated.

Is there a command to know who's connected on OVPN server? and eventualy to force a disconnection?
I read somewhere VPN user is for one simultaneous connection.

thanks a lot for help

Well finally problem is due to only one connection is allowed so now i'd like to know if there's a command to see who's connected to OVPN server?

And is there a way to allow several connections as other OVPN users are not allowed once the first one is connected. Do i need to open as many TCP ports as users i have?
