OPENVPN error: Address already in use

Hello,

I setup a vpn server using the Wizard on my Netgate SG-2440.

I download the client but im getting the following error:

Sun Jun 18 12:19:30 2017 OpenVPN 2.3.12 x86_64-w64-mingw32 [SSL (OpenSSL)] [LZO] [PKCS11] [IPv6] built on Aug 23 2016

Sun Jun 18 12:19:30 2017 library versions: OpenSSL 1.0.1t 3 May 2016, LZO 2.09
Enter Management Password:

Sun Jun 18 12:19:39 2017 TCP/UDP: Socket bind failed on local address [undef]: Address already in use (WSAEADDRINUSE)
Sun Jun 18 12:19:39 2017 Exiting due to fatal error

Any advice?

Thanks

That error is from the client, not pfSense.

Something else is already using the address/port it wants.

Also your Windows OpenVPN client is very out of date and vulnerable. Uninstall that and install the latest version. If you installed it from the client export package, update your export package and then export a new installer. Use the 2.4 installer if you can.
