[squid-users] ICAP Service Chaining Issue

I am getting the following error when chaining qlproxy and squidclamav
services. If I was to configure just qlproxy or just squidclamav
service, it works. Note, this is a rare case as for the most part
everything works fine. I am guessing because I hit mixed content
(http and https). The configuration is below.

ICAP protocol error.

The system returned: (100004) Unknown error 100004

This means that some aspect of the ICAP communication failed.

Some possible problems are:

The ICAP server is not reachable.

An Illegal response was received from the ICAP server.
