Hello LA, Yuri,
The server analysis at https://www.ssllabs.com/ssltest/analyze.html?d=help.ea.com&s=126.96.36.199&latest shows the certificate chain presented by the remote server is indeed incomplete, specifically the following certificate is not presented:
Symantec Class 3 Secure Server CA - G4
Fingerprint SHA256: eae72eb454bf6c3977ebd289e970b2f5282949190093d0d26f98d0f0d6a9cf17
Pin SHA256: 9n0izTnSRF+W4W4JTq51avSXkWhQB8duS2bxVLfzXsY=
RSA 2048 bits (e 65537) / SHA256withRSA
Adding it to the intermediate certificate file as indicated on https://docs.diladele.com/faq/squid/fix_unable_to_get_issuer_cert_locally.html#way-1-add-missing-certificate-to-squid-web-safety-5-1-recommended and reloading Squid 3.5.23 allows to successfully see and bump the site.
Our UI generates exactly the same config setting as you have tried:
So it must be working :)

Got an error message from squid where I'm doing https-bumping:
The following error was encountered while trying to retrieve the URL:
*Failed to establish a secure connection to 188.8.131.52*
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=US/O=Symantec Corporation/OU=Symantec Trust Network/CN=Symantec
Class 3 Secure Server CA - G4
This proxy and the remote host failed to negotiate a mutually acceptable security settings for handling your request. It is possible that the remote host does not support secure connections, or the proxy is not satisfied with the host security credentials.
Used openssl.com to get the intermediate certs (2 hosts are referenced in parallel chains). The two certs looked like:
Added the certs to a file and that filename to my squid.conf on a line:
restarted squid, but am still getting same error.
Am I missing some obvious step?
Looking for a clue... ;-)
