Hello, can anyone supply me an idea what to look for/at to solve the below issue? (keep in mind, that I am not using the Leap Java bundles/versions) Steps taken: 1. Go to https://<server>/rhn/kickstart/CreateProfileWizard.do 2. Follow the wizard to the end past the password screen 3. Click on Finish Expectation: New profile shows up and can be Uyuni-managed Reality: "Internal Server Error" shows up. On loading the profile screen, the profile is there but cannot be Uyuni-managed. /var/log/cobbler/cobbler.log does not seem to show anything releavant (errors). /var/log/rhn/web* did not get any new entries or have not been created after deletion and restart. /var/log/tomcat/catalina.2023-02-16.log 16-Feb-2023 09:31:33.473 SEVERE [http-nio-127.0.0.1-8080-exec-1]
