Enable verbose SSL. Start Tomcat with -Djavax.net.debug=ssl. That will print a lot of info to catalina.out.
You could also do the same thing on the client side if you used a java client, or something similar with OpenSSL, curl, etc. -----Original Message----- From: Steve Willett [st...@yoursportsleague.com<mailto:st...@yoursportsleague.com>] Sent: Tuesday, November 15, 2016 05:48 PM Central Standard Time To: users@tomcat.apache.org Subject: Problems with SSL configuration I am trying to set up a stand-alone Tomcat server (apparently 7.0.53). When I set up a simple Connector on port 8443 (no specified ciphers, and a simple sslProtocol="TLS") using a DigiCert Certificate I can connect. However, if I test it with QualSys, I get an F rating because of the accepted insecure cipher suites. However, when I try to use "approved" suites, the server can't be reached.
