[squid-users] Forwarding loop error after upgrading to 3.2.13 or 3.3.8

I have parent child squid installation.

LAN->squid1->squid2->Internet.
                             ^
                             ^
                           WAN

squid2 works as a transparent proxy for WAN connections.

I was using 3.2.13 for squid2 (child) and 3.1.23 (parent). Every thing
works correctly.

But, if i upgrade the parent to 3.2.13 or 3.3.8, i always get this error:

otacon is the hostname of child squid.
solidus is the hostname of parent squid.

The error only occur from LAN connection. Things work greatly for any
WAN connection (with squid 3.1.23, 3.2.13, or 3.3.8).
