I have configured squid with ssl-bump (intercept mode) and it works as expected while accessing secure sites from browsers. What I have done so far. - Configured squid. - created a root& intermediate certificate for dynamic cert generation in squid. installed the same root certificate in mobile device(iphone 6 -iOS-10). - Every website works on chrome/safari. But apps like facebook,twitter are not working(showing network error). When checking cache log of squid, I found the below log. /Error negotiating SSL connection on FD 12: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca (1/0) / It looks like initial CONNECT/Handshake is not working. what I have changed in squid.conf ----------------------------------------------------------------- acl localnet src 172.16.0.0/12 acl localnet src fe80::/10 acl allow localnet ssl_bump bump all always_direct allow all http_port localhost:3128 http_port localhost:3129 intercept https_port localhost:3130 intercept ssl-bump generate-host-certificates=on cert=/etc/squid/cert/cert.pem key=/etc/squid/cert/key.pem strip_query_terms off ---------------------------------------------------------------- Any idea how to fix this? or where to check? What might be my mistake ? PS: I use squid to get logs of all internet traffic from mobile devices.
