[squid-users] SQUID3 and https: Error negotiating SSL connection

Hi,
I'm new in Squid configuration and I have problems with HTTPS sites. I
searched a lot but I didn't find a solution.
I can't open any https site and I have different error messages in different
browsers:
    - in firefox www.gmail.com returns ssl_error_bad_cert_domain
    - in chrome www.gmail.com returns "The site's security certificate is
not trusted!"
    - in firefox www.facebook.com returns "The page isn't redirecting
properly"
    - in chrome www.facebook.com returns "This webpage has a redirect loop"
(Error 310 net:: ERR_TO_MANY_REDICTS)

In cache.log there are these messages:
    /2013/02/19 16:02:15| clientNegotiateSSL: Error negotiating SSL
connection on FD 16: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert

My squid.conf is:

My ip-table config is:
/ -t nat -A PREROUTING -i LAN -p tcp --dport 443 -s ! 192.9.200.2 -j
REDIRECT --to-port 8081
    -t filter -A FORWARD -s 192.9.200.0/24 -d 192.9.200.2 -i LAN -o LAN -p
tcp --dport 8081 -j ACCEPT /

For ssl certificate I used this
<http://shirker.blog.com/2011/11/10/generate-ssl-certificate-for-squid/>
page.

How can I solve my problem?
Thank you very much!
Skylab
