Hi av,

have had the same issue due to authenticate any user before passing the proxy. Squid couldn't fetch the intermediate certificates.
I added the following in squid.conf before the line "acl Authenticated_Users proxy_auth REQUIRED":

#Allow fetch intermediate certs before required authentication
acl fetched_certificate transaction_initiator certificate-fetching
cache allow fetched_certificate
http_access allow fetched_certificate

Hope this helps you too.

Lot regards
