It works in 5.8 with no errors however in 6.6 I can see indexing and other information that I have never seen before realted to my cache and this new TLS error that follows your thought process you listed before with OpenSSL

I would love to learn more I am a Computer science student with a AA in cyber security I have worked in the IT field for the past 15 years, I have some open pull requests in for Squid here
This proxy technology fascinates me so much. It is amazing code.
And
https://github.com/pfsense/FreeBSD-ports/pull/1366 Fix for non support 2024/04/05 07:58:24| ERROR: Unsupported TLS option SINGLE_DH_USE
2024/04/05 07:58:24| ERROR: Unsupported TLS option SINGLE_ECDH_USE
Again I do not think many development team members review any of the GitHub pulls for Squid or I am working on something else
if anyone wants to let me know what part of the cipher should be removed please let me know so I can fix the RC4 issue. https://github.com/pfsense/FreeBSD-ports/pull/1365 Working on this also Per Squid support Amos Jeffries "Also there are a few weird things in your TLS cipher settings, such as this sequence " EECDH+aRSA+RC4:...:!RC4 "
Which as I understand, enables the EECDH with RC4 hash, but also forbids all uses of RC4." Are we to disable RC4 because of the security issues? Or are we leaving it it has both listed. if (empty($settings['sslproxy_compatibility_mode']) || ($settings['sslproxy_compatibility_mode'] == 'modern')) {
$sslproxy_cipher = "EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aRSA:!RC4:!aNULL:!eNULL:!LOW:!3DES:!SHA1:!MD5:!EXP:!PSK:!SRP:!DSS";
$sslproxy_options .= ",NO_TLSv1";
} else {
$sslproxy_cipher = "EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aRSA:HIGH:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS";
}
Anything else you need I think you requested a pcap file I will create one with 2000 entries of facebook or something also

I do not know the answer to your question. I speculate that it could be related: Depending on various factors, without those DH parameters, Squid may not be able to communicate with clients. See WARNING in tls-dh description in squid.conf.documented. I know that others are reporting similar WARNINGs during v6 upgrades and dislike the letters "EC" those messages use. I am not going to debate the best choice of letters for this message, but I can tell you that, in the cases I investigated, the message was caused by a mismatch between squid.conf tls-dh=... option value and DH parameter file contents: * To Squid, tls-dh=curve:filename format implies that the keytype is "EC". These two letters are then fed to an OpenSSL function that configures related TLS state. OpenSSL then fails if tls-dh filename contains DH parameters produced with "openssl dhparam" command. I have seen these failures in tests. * To Squid, tls-dh=filename format (i.e. format without the curve name prefix) implies that the keytype is "DC". These two letters are then fed to an OpenSSL function that configured related TLS state. OpenSSL then probably fails if tls-dh filename contains DH parameters produced with "openssl ecparam" command. I have not tested this use case. * The failing checks and their messages are specific to Squids built with OpenSSL v3. It is possible that Squids built with OpenSSL v1 just silently fail (at runtime), but I have not checked that theory. FWIW, this poorly categorized message indicates a configuration _error_. AFAICT, Squid code should be adjusted to _quit_ (i.e. reject bad configuration) after discovering this error instead of continuing as if nothing bad happened. I recommend addressing the underlying cause, even if this message is unrelated to SQUID_TLS_ERR_ACCEPT+TLS_LIB_ERR=A000417. HTH, Alex.

I think I have seen that error code before, but I do not recall the exact circumstances. Sorry! The error happens when Squid tries to accept (or peek at) a TLS connection from the client. Might be prohibited TLS version/feature, TLS greasing, or non-TLS traffic? Try examining client TLS Hello packet(s) in Wireshark.
