[squid-users] Cert authority invalid failures.

I'm curious as to why this is happening.
Proxy was implemented last week and since then I've been dealing with all the sites that don't work. Not a problem, knew it was going to happen. I'd like to understand why the following is happening.
1. User goes to https://www.whatever.com
2. Browser, mostly chrome, gives the following error. Connection not private. NET:ERR_CERT_AUTHORITY_INVALID
3. If you view the cert it shows the dynamic cert listed.
4. Click the "Proceed to www.whatever.com<http://www.whatever.com> (unsafe )
5. Now I get a squid error. Requested url could not be retrieved. Access denied while trying to retrieve https:// some ip address/*
Thing is I don't have an acl blocking that ip? ( Small sub question here, is there a way to tell which acl blocks something? )
What I've had to do to get around this is add www.whatever.com<http://www.whatever.com> to my broken_sites.acl. Then add the ip to an allowed_ips.acl.
Then I http_access allow the ips list
And skip peeking at the broken site.
acl broken_sites ssl::server_name_regex "/etc/squid3/acls/http_broken.txt"
ssl_bump peek !broken_sites
ssl_bump splice all
I'm trying to understand why this is breaking and if I'm doing the right thing in fixing it.
The second error I'm getting is:
The following error was encountered while trying to retrieve the URL: https://*.agentimediaservices.com/*<https://%2A.agentimediaservices.com/*>
Failed to establish a secure connection to 126.96.36.199
The system returned:
(71) Protocol error (TLS code: X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY)
SSL Certficate error: certificate issuer (CA) not known: /C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Organization Validation Secure Server CA
Same question. From what I've read this means that I don't have the correct root ca? Is that correct? If so is the fix to then go try to find the correct .crt and add it to the standard ca-cert store? ( I'm on debian so /usr/share/ca-certificates/Mozilla )
Again, is this correct as to what is going wrong and the correct fix?
