From: Cherukuri, Naresh
Hi All, I installed Squid version 3.5.20 on RHEL 7 and generated self-signed CA certificates, My users are complaining about certificate errors. When I looked at cache.log I see so many error messages like below. Below is my squid.conf file. Any
ideas how to address below errors.
