> This complain and Remote Access in (so I can SSH to my $4k MacBook) disables itself anytime the computer is restarted.
I've found IPv6 stops working after sleep, the appropriate area in the network pane is blank (I use RA not DHCPv6). Since the Mac updates its DNS records and puts IPv6 addresses in I've found accessing via hostname stops working, but then of course I can use the IPv4 address which works fine.
Yep. I turned off ipv6 support on my router an computers, and still use RA. No more issues on local network except one ... the DNS settings on my MacBook constantly revert to a default value, killing my host name access to my docket containers. But at least it’s a quick fix.
