Running Jira applications over SSL or HTTPS | Administering Jira applications Data Center 11.3 | Atlassian Documentation

 

I've use this guide from upgrading our test env from 10.3x to 11.3.x and tomcat will not start up. I keep getting a certificate type is undefined and the service won't start up. Any ideas how to fix this error?

The server.xml SSL configuration is different for Tomcat 10.

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" scheme="https" secure="true" SSLEnabled="true"> <SSLHostConfig keystoreFile="path/to/your/keystore.jks" keystorePass="your_keystore_password"/> </Connector>

Above is an example of what it should look like now, see docs for more
