Thanks! Let's see, here it starts to do DNS to identify which interface to
listen on:
> open("/etc/host.conf", O_RDONLY|O_CLOEXEC) = 5
> fstat(5, {st_mode=S_IFREG|0644, st_size=9, ...}) = 0
> mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
> 0x7f8e66910000
> read(5, "multi on\n", 4096) = 9
> read(5, "", 4096) = 0
> close(5) = 0
> munmap(0x7f8e66910000, 4096) = 0
> futex(0x7f8e64cf5ac4, FUTEX_WAKE_PRIVATE, 2147483647) = 0
> open("/etc/resolv.conf", O_RDONLY|O_CLOEXEC) = 5
That goes on for a while...

So it tried four times and your private DNS is still failing.
Please fix the DNS server!
Maybe it was shut down for upgrade as well?
Another thing, it DID tell the reason to systemd. Wasn't there a message in
systemctl status output?

Eduard.
