Severe error due to SSL Certificate

Andrea C May 1, 2018


I installed the SSL certificate in crowd and it worked fine, but as soon as I rebooted the server (wanted to check if crowd was starting automatically), it didn't start back and it was giving me the following error:

SEVERE [main] org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["https-jsse-nio-8443"]

ava.lang.IllegalArgumentException: None of the [ciphers] specified are supported by the SSL engine : (and a huge list of ciphers).


I can delete my keystore and start again but I'm just struggling to understand which commands I should use. I need to create a keystore, create a csr and once the certificates are issued, which ones I should import and install?


The connector <crowd installation>/apache-tomcat/conf/server.xml I just followed this documentation:

so it looks like this:

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
           maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           clientAuth="false" sslProtocol="TLS"
           keystoreFile="${user.home}/.keystore" keystorePass="changeit"
           keyAlias="tomcat" keyPass="changeit"/> 

of course the keystoreFile points to my keystore.


Thanks for your help.

Hi Andrea, 

I have a feeling that the issue is not your keystore, but rather the protocol defined in the connector in server.xml.

Your connector directive looks the same as in the document, but I think the guide may be outdated (will follow up with doc team after we get you sorted). The example connectors in the Tomcat Guide all use other protocols. The example files for other Atlassian products use:


instead of 


The protocol you are using has caused issues with Jira starting up (Tomcat will not start in 7.3 with protocol="org.apache.coyote.http11.Http11Protocol") so I recommend changing it and restarting Crowd. I look forward to hearing the result.

Hi Ann,

I resolved by changing the protocol and added the cyphers.

My connector looks like this:

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocols="TLS"
keystoreFile="${user.home}/.keystore" keystorePass="changeit"
keyAlias="tomcat" keyPass="changeit"/>


May I suggest that the documentations should be updated? I spent so many hours on this and it's not easy to troubleshoot.

Also, it would be really appreciated a much more in dept documentation on how to generate the keystore, how to generate the csr and how to import and install the certificates.

It's just a few command lines but there's so many options that it would nice to know which ones are the most accurate and up-to-date ones.
