If you still can connect with the vpn server then it is probably the same issue than in this thread:On my 86U the openVPN seems to freeze showing this message:
Initialinzing the settings of OpenVPN server now, please wait a few minutes to let the server to setup completed before VPN clients establish the connection.
This message does not go away unless I reboot my router.
