There are a couple of things to check. * you have correct and most recent signing authority certificates etc to verify theirs against. * your SSL library being used by Squid is capable of SSLv3 9which their site appears to require) There is a slim chance it could actually be a case of site forgery (your upstream doing SslBump would be pure irony). > > My certificate is my company wildcard certificate.
