Question

i have install tomcat 8(ssl support) with java 1.8. When start tomcat catalina out write

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

and this

With old version of tomcat and java errors don't occur.

My server.xml configuration

    <Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="700" scheme="https" secure="true"

What could be the problem? Thanks

TLSv1+TLSv1.1+TLSv1.2 should be TLSv1,TLSv1.1,TLSv1.2. Is it a typo? If it is, probably the cipher suite you have set has no correspondence in server – Alpestrine

Answer 1

From the Apache Tomcat 8 Configuration Reference, sslEnabledProtocols should represent

The comma separated list of SSL protocols to support for HTTPS connections.

The Apache Tomcat 8 - Security Considerations document has an example indicating the correct usage of this parameter -- sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2". You have this incorrectly specified to use + instead of , -- TLSv1+TLSv1.1+TLSv1.2.
