Many third party OpenVPN client applications are updating and no longer accept lower level encrypted certificates which was generated on version 12 or earlier of Untangle. Even if you upgraded your Untangle to the latest version, the OpenVPN certificate is still the same as we do not generate a new certificate on upgrade so OpenVPN connections won't break. Thus some OpenVPN connections will fail due to third party VPN clients restrictions.
The solutions is to generate a new OpenVPN certificate and redistributing the OpenVPN config files for each OpenVPN user.
Steps:
- Export the server remote clients, groups, and networks from /admin/index.do#service/openvpn/server
- Remove OpenVPN app from Untangle by clicking the remove button at the bottom of /admin/index.do#service/openvpn/status
- Install OpenVPN again.
- Import all the previous exports for server remote clients, groups, and networks
- Send the new client config files to your OpenVPN clients.
