Hi! I just upgraded to 25.1.1 but found that openVPN no longer works. Service exit with the following errors:
2025-02-12T14:25:55-06:00 Notice openvpn_client1 Exiting due to fatal error
2025-02-12T14:25:55-06:00 Error openvpn_client1 Cannot open TUN/TAP dev /dev/tun1: Device busy (errno=16)
2025-02-12T14:25:55-06:00 Notice openvpn_client1 TUN/TAP device ovpnc1 exists previously, keep at program end
2025-02-12T14:25:55-06:00 Error openvpn_client1 Options error: Unrecognized option or missing or extra parameter(s) in [PUSH-OPTIONS]:9: block-outside-dns (2.6.13)

2025-02-12T14:25:53-06:00 Warning openvpn_client1 WARNING: this configuration may cache passwords in memory -- use the auth-nocache option to prevent this
I'm using "Clients (legacy)" under OpenVPN, Most of the error/warning existed prior to 25.1.1, the only new and fatal error is
openvpn_client1 Cannot open TUN/TAP dev /dev/tun1: Device busy (errno=16)
I was upgraded from 25.1 and OpenVPN worked well before the upgrade. Besides OpenVPN, Tailscale, Wireguard, and IPsec(VTI) tunnels are also running on the same server.
Seems fixed by restarting a couple of times.
Same her !
Thanks for help
