Hi Amos

Thanks for your input, I did recompile

See :

Squid Cache: Version 3.5.15-20160302-r14000

Service Name: squid

configure options:  '--prefix=/squid' '--includedir=/squid/usr/include'
'--enable-ssl-crtd' '--datadir=/squid/usr/share' '--bindir=/squid/usr/sbin'
'--libexecdir=/squid/usr/lib/squid' '--localstatedir=/squid/var'
'--sysconfdir=/squid/etc/squid' '--enable-arp-acl'
'--enable-follow-x-forwarded-for' '--enable-auth'
'--enable-auth-basic=DB,LDAP,NCSA,PAM,RADIUS,SASL,SMB,getpwnam'
'--enable-auth-ntlm=smb_lm,fake'
'--enable-auth-digest=file,LDAP,eDirectory'
'--enable-auth-negotiate=kerberos'
'--enable-external-acl-helpers=file_userip,LDAP_group,session,unix_group,wbinfo_group'
'--enable-cache-digests' '--enable-cachemgr-hostname=localhost'
'--enable-delay-pools' '--enable-epoll' '--enable-icap-client'
'--enable-ident-lookups' '--enable-linux-netfilter' '--enable-referer-log'
'--enable-removal-policies=heap,lru' '--enable-snmp' '--enable-ssl'
'--enable-storeio=aufs,diskd,ufs' '--enable-useragent-log'
'--enable-wccpv2' '--enable-esi' '--with-aio' '--with-default-user=squid'
'--with-filedescriptors=64000' '--with-dl' '--with-openssl'
'--with-pthreads' 'build_alias=x86_64-redhat-linux-gnu'
'host_alias=x86_64-redhat-linux-gnu' 'target_alias=x86_64-redhat-linux-gnu'
'CFLAGS=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fpie'
'CXXFLAGS=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fpie'
'PKG_CONFIG_PATH=/usr/lib64/pkgconfig:/usr/share/pkgconfig'
'--enable-ltdl-convenience' '--disable-ipv6'


Yes the IP in question is my squid IP, I am still getting the same error,
it is as if squid sends traffic to itself

Only difference is that I see this in access log now

1457080684.426      0 84.208.223.203 TAG_NONE/200 0 CONNECT
162.220.xx.xx:443 - ORIGINAL_DST/162.220.xx.xx -

Not sure if this means anything .
