Daniel,

Thanks for forwarding this, This seems to have been fixed in the last couple days. I still find it strange that the ipv6.connman.net has an ipv6 *and* an ipv4 address.
Name:   ipv6.connman.net
Address: 87.106.208.187
Name:   ipv6.connman.net
Address: 2001:8d8:8b4:c861:5826:fa5f:6690:0

Regardless, I no longer get the:
connmand[267]: Failed to find URL:http://ipv6.connman.net/online/status.html

in my logs and we will see if it has any effect on the reconnection and 'online' testing that connman does.
