-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 With intermediate certificates better to use sslproxy_foreign_intermediate_certs for many reasons: 1. sslproxy_foreign_intermediate_certs not treated as trusted root CA's. They only uses for complete certificate chain. 2. Intermediate CA's most often has relatively short expiration, so better do not mix it with root's. 3. IMHO separate intermediate bundle has less maintenance overhead. # sslproxy_foreign_intermediate_certs backported from 4.x starting 3.5.13 sslproxy_foreign_intermediate_certs /usr/local/squid/etc/intermediate_ca.pem I've published here download link to my intermediate_ca.pem I'm using in my setups. I'm not pretend this bundle is full, but I'm updating it when meet UNABLE_TO_GET_ISSUER_CERT_LOCALLY. Note: You need to check intermediate CA's expiration/revocation youself. So, to do this you need all source intermediates separately. This time there is no tool to build this bundle automatically, like Mozilla's CA bundle. Note 2: Don't - I repeat - DONT USE dont_verify_peer in production setups. Never. This is dangerous. 29.04.16 2:56, Rafael Akchurin пишет: > > Hello Bruce, > > > > According to https://www.ssllabs.com/ssltest/analyze.html?d=agentimediaservices.com the server does not send the whole chain of certificates and imho squid cannot automatically download the intermediate certificates like browsers do. > > > > You need to manually add them to the store.

I’m also confused as to why this is happening. My ca store is up to date. I’m confused as to why this is happening. If I can access all these sites fine without the proxy I’d have to think it’s not the cert itself. So it’s either debians cert store or something else.
