And the bug you reported previously was fixed. That bug involved a IPv4 socket, you provided a system call trace and a possible fix that was applied with minor changes of the order of the tests in the if clause.
This report is against a IPv6 socket base on the clients address. You first reported this to us ~16 hours ago according to gitlab. Lets move the discussion of this issue back to the issue tracker.
