OpenVPN server-ipv6 breaks server's IPv6 connecivity

Hi, as I added a random ULA subnet to my OpenVPN configuration, the IPv6 breaks if the OVPN server is started.

ovpn server stopped

root@debian-s-1vcpu-1gb-fra1-01:/etc/openvpn# ping6 2001:4860:4860::8888 PING 2001:4860:4860::8888(2001:4860:4860::8888) 56 data bytes 64 bytes from 2001:4860:4860::8888: icmp_seq=1 ttl=61 time=0.649 ms 64 bytes from 2001:4860:4860::8888: icmp_seq=2 ttl=61 time=0.668 ms ^C — 2001:4860:4860::8888 ping statistics — 2 packets transmitted, 2 received, 0% packet loss, time 1026ms rtt min/avg/max/mdev = 0.649/0.658/0.668/0.027 ms

ovpn started

root@debian-s-1vcpu-1gb-fra1-01:/etc/openvpn# systemctl start openvpn@server root@debian-s-1vcpu-1gb-fra1-01:/etc/openvpn# ping6 2001:4860:4860::8888 PING 2001:4860:4860::8888(2001:4860:4860::8888) 56 data bytes ^C — 2001:4860:4860::8888 ping statistics — 4 packets transmitted, 0 received, 100% packet loss, time 3066ms

The only line I’ve changed in my ovpn.conf is the following, which is a random ULA subnet: server-ipv6 fdb0:e445:f404:83b1::/64

Any clues?
