Sylvain Rochet commented on INFRA-11567:
----------------------------------------

Oh dear, it is working today. I previously tested from all the IPv6 hosts I have access to and it didn't work anywhere and now it is flawlessly working.

What I can tell is it wasn't working for at least some weeks, I had to debug an apache module (outside of the Apache source tree) and extensively used the APR documentation during that and had to remove my IPv6 default route during all this time.

My primary source IPv6 address is 2a01:e35:2f0a:58e0:1::2, not tunneled at all. Do you have something in your httpd logs for the past few weeks from this host ?

> That's a problem, because most browsers don't failback to IPv4 if the IPv6 TCP session is properly established but hang forever. Currently, all IPv6 enabled browsers can't access to anything hosted on 2a01:4f8:130:2192::2 at all
