Hi !
I have OMV 4 and I installed :
- haugene/transmission-openvpn (in a docker) to use transmission through a VPN (Private VPN). Other data don't use the VPN
- OpenVPN pluggin to use my NAS as a VPN Server when I need to access my network from outside.
My problem :
- When transmission is running , the OpenVPN pluggin is no longer working ...
These "two OpenVPN" (client for transmission and server for the pluggin) should interfere but I have no idea to solve the problem ... 
Thanks for your incoming help ...
