Can you confirm that squid is able to resolve these hostnames? If not try browsing to them without https and check if squid gives you an error message.
Did you check the cache.log as well?

Hi All,
We have the following setup of a transparent squid box:
OS: CentOS release 6.9 (Final)
Squid Cache: Version 3.5.26-20170625-r14174
Compile options:
'--with-included-ltdl' '--enable-icap-client'
'--enable-delay-pools' '--with-openssl' '--enable-ssl-crtd'
'--enable-icmp' '--enable-snmp' '--prefix=/usr'
'--includedir=/usr/include' '--datadir=/usr/share'
'--bindir=/usr/sbin' '--libexecdir=/usr/lib/squid'
'--localstatedir=/var' '--sysconfdir=/etc/squid'
--enable-ltdl-convenience
Endpoints are redirected to the Squid box using a policy route for
TCP80/443 on a Fortigate firewall. All http/80 traffic works well. We
are using ssl bump for ssl, but there is an strange behavior, some
websites opens well, but some ones breaks and getting TAG_NONE/503
errors in the access log:
