I found that if I have ListenStream=192.168.1.198:5901 in my xvnc.socket file I also
get a failure on boot. I thought it could have been due to my using DHCP on that
VM. I changed it back to ListenStream=5901. Can you try just having that?
Odd that you're getting an IPV6 error message. I don't have a global IPv6 address
and only show....
[egreshko@f25f system]$ ip address show enp0s3
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group
default qlen 1000

valid_lft 84207sec preferred_lft 84207sec
inet6 fe80::a00:27ff:fe15:6de0/64 scope link

FWIW, after being summoned for breakfast I did add "Type=simple" and things still
worked for me.
