DOn't know if this is the right place or not, but since moving to connman, I have noticed that the ipv6 test page is down. the ipv4 one works fine, but I get a mention in the log:
"connmand[254]: Failed to find URL:http://ipv6.connman.net/online/status.html"

If I try to get to it from a browser, I get a '502 bad gateway error'

If I use curl on the cli, I get this:
# curl ipv4.connman.net/online/status.html
<html>
<head>
</head>
<body>
</body>
</html>
# curl ipv6.connman.net/online/status.html
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx</center>
</body>
</html>

I think something is not set right on the server...
