Hi, I desperately need help...
I have 10 staff (before covid it was 1-2) who are currently connecting to a QNAP via its OpenVPN implementation. Always worked fine but recently had to change to split tunnel to accommodate the extra traffic. Very difficult to edit the server.conf as I have to ssh in to do it and it gets replaced to default on reboot... so that file is default for QNAP OpenVPN.
client
dev tun2001
script-security 3
proto udp
remote xxx.xx.xx.xx 1194
resolv-retry infinite
nobind
ca ca.crt
route 192.168.0.0 255.255.254.0
auth-user-pass
reneg-sec 0
cipher AES-128-CBC
tls-cipher TLS-SRP-SHA-RSA-WITH-3DES-EDE-CBC-SHA:TLS-DHE-RSA-WITH-AES-128-CBC-SHA:TLS-DHE-RSA-WITH-AES-256-CBC-SHA
Worked perfectly for all staff for a day after the change then suddenly its stopped working, the TAP adapter never gets an IP:

Can someone please tell me why the TAP adapter fails to get an IP now suddenly when yesterday it worked absolutely fine?
