Hi, I have setup a squid server (squid-3.5.26-20170702-r14182) to filter http/https. It was working fine with up to 90 users except one thing. Few PCs would not be able connect to https sites (e.g google,yahoo,facebook) intermittently. By clearing SSL State in user PCs (Windows->Control Panel->Internet Properties) , it helps sometime (sometime not). Please advice. Thank you. my squid setup ---------------- (WAN)---(router)---(linux+bridge+squid)---(user) e.g access.log --------------- 1502955689.139 0 10.40.21.24 TAG_NONE/409 4088 CONNECT www.google.com:443 - HIER_NONE/- text/html my squid.conf --------------- max_filedesc 65535 dns_v4_first on request_timeout 5 minutes acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT http_access deny !Safe_ports http_access allow localhost manager http_access allow localnet manager http_access deny manager http_access allow localnet http_access allow localhost http_access deny all http_port 0.0.0.0:3128 intercept http_port 0.0.0.0:3130 https_port 0.0.0.0:3129 intercept ssl-bump connection-auth=off cert=/etc/squid/squidCA.pem cache_mem 256 MB always_direct allow all sslproxy_cert_error allow all sslproxy_flags DONT_VERIFY_PEER acl test ssl::server_name "/etc/squid/test.txt" acl step1 at_step SslBump1 ssl_bump peek step1 ssl_bump terminate test ssl_bump splice all sslcrtd_program /usr/lib/squid/ssl_crtd -s /var/lib/ssl_db -M 4MB cache_dir ufs /var/spool/squid 15360 16 256 cache_swap_low 87 cache_swap_high 90 coredump_dir /var/spool/squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 url_rewrite_program /usr/bin/squidGuard redirect_program /usr/bin/squidGuard -c /etc/squidguard/squidGuard.conf -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Intermittent-409-Error-to-google-com-tp4683329.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
