Seems to me the remote site isn't responding to your VPN request.
Oct 16 17:34:32 gauss nm-openvpn[3260]: UDPv4 link remote: [AF_INET]85.188.1.118:1773 Oct 16 17:35:11 gauss NetworkManager[912]: <warn> VPN connection 'AMPRNet' connect timeout exceeded.
I'm not currently using this VPN service but can you reach / ping 85.188.1.118 ? It pings for me but a telnet (TCP) connection attempt to port 1773 is refused from my IP.
