Did the 2001:db8:38a5:8::2006 address actually get assigned to lo on the 
realserver? If not you have probably not yet disabled DAD (duplicate address 
detection) for lo on the realserver:

echo 0 > /proc/sys/net/ipv6/conf/lo/dad_transmits  
echo 0 > /proc/sys/net/ipv6/conf/lo/accept_dad   

This should be done before configuring the IPv6 addresses, somewhat like the 
way you would change ARP configuration for IPv4.  

Also I would recommend using TCP to test the configuration as you might get 
more feedback on the client if something goes wrong.

Kind regards,
