Peace, my squid certificate has expired, so i regenerated a new one and
tried to enable ssl bump without success.
here is the configuration:
http_port 8080 ssl-bump cert=/etc/squid/certs/myCA.pem
generate-host-certificates=on dynamic_cert_mem_cache_size=8MB
acl tls_s1_connect at_step SslBump1
acl tls_s2_client_hello at_step SslBump2
acl tls_s3_server_hello at_step SslBump3
# define acls for sites that must not be actively bumped
acl tls_allowed_hsts ssl::server_name .akamaihd.net
acl tls_allowed_hsts ssl::server_name .proxy.skko.by
acl tls_server_is_bank ssl::server_name
"/usr/local/ufdbguard/blacklists/finance/domains.squidsplice"
acl tls_to_splice any-of tls_allowed_hsts

# properties of

can (if the stare succeeded)
