[squid-users] A bunch of SSL errors I am not sure why

Hello,

Bypassed is non-intercepted right? The site worked fine when it was added to the bypass list.
Other .gov.co<http://gov.co> sites have the same issue, and I have to add them to bypass list for clients to be able to access them.

Here’s the error page before adding to the bypass list:

@Amos:


* Check that the set of "global trusted CA" installed on your Squid machiene is up to date.

How can I do that? I recreated the Certs DB and no luck.


* Try the latest Squid-4, which can auto-download intermediate certificates.

Is squid 4 stable for production?

When the proxy is defined in the browser.
Can you verify if it affects only intercepted connections or also non-intercepted ones?

Hello Eliezer, all,


I removed the cipher and the problem is still there:

The CA used to sign the remote endpoints certificate is not trusted. Or an intermediary certificate is missing.

* Check that the set of "global trusted CA" installed on your Squid machiene is up to date.

* Try the latest Squid-4, which can auto-download intermediate certificates.

The obsolete SSL protocol is being used.

The client disconnected. You can do nothing about that.

"certificate verify failed" says what it means.
