Thank you Amos and Alex for great help & support so far. As per suggestions I have added lot more parameters in squid.conf for both "http" & "tls_outgoing_options" directives: http_port 3128 ssl-bump \ tls-cert=/usr/local/squid/etc/ssl_cert/myCA.pem \ cipher=HIGH:MEDIUM:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!DH:!ADH \ options=NO_SSLv3,SINGLE_DH_USE,SINGLE_ECDH_USE \ generate-host-certificates=on dynamic_cert_mem_cache_size=4MB \ tls-cafile=/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \ tls-dh=prime256v1:/usr/local/squid/etc/dhparam.pem \ tls-dh=secp384r1:/usr/local/squid/etc/dhparam.pem tls_outgoing_options \ default-ca=off \ cafile=/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \ options=NO_SSLv3,SINGLE_DH_USE,SINGLE_ECDH_USE \ cipher=HIGH:MEDIUM:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!DH:!ADH \ flags=DONT_VERIFY_DOMAIN \ flags=DONT_VERIFY_PEERi \ min-version=1.2 Now, when I look into wireshark between Server <--> Squid; I no longer see error: 61 Alert (Level: Fatal, Description: Internal Error) sent by Squid Only issue is Squid sends: 2018-11-02_151705.jpg <http://squid-web-proxy-cache.1019090.n4.nabble.com/file/t377591/2018-11-02_151705.jpg> How to make Squid send certificate in it? -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
