Hi, Today I just migrated from Squid 3 to Squid 4, and I found that a reverse proxy that was working fine before is now failing. The client browser sees this message: [No Error] (TLS code: SQUID_ERR_SSL_HANDSHAKE) Handshake with SSL server failed: [No Error] This is how I configured the backend: cache_peer 10.215.144.16 parent 443 0 no-query originserver login=PASS ssl sslcert=/etc/ssl/MY-CA/certs/W1_cert.cer sslkey=/etc/ssl/MY-CA/certs/W1_key_nopassphrase.pem sslcafile=/etc/ssl/MY-CA/cacert.pem ssloptions=NO_SSLv3,NO_SSLv2,NO_TLSv1_2,NO_TLSv1_1 sslflags=DONT_VERIFY_PEER front-end-https=on name=MyServer The NO_TLSv* options are because the backend server is an old Windows 2003 (which hasn't changed either). How can I debug this? Vieri _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
