Сan not save the proxy port number for the vpn connection
Xubuntu 18.10 x86_64 GNU/Linux 4.18.0-13-generic
network-manager-openvpn is already the newest version (1.8.6-1ubuntu1).
network-manager-openvpn-gnome is already the newest version (1.8.6-1ubuntu1).
openvpn is already the newest version (2.4.6-1ubuntu2).
network-manager is already the newest version (1.12.4-1ubuntu1.2).
I'm using a VPN on a corporate proxy, while trying to define the required port on the OpenVPN Advanced Options tab to port 8080 it keeps resetting to port 120. Because of this error I cannot use the VPN.
