HTTP 404 error

[HB_13182386]

After installing CB 3 on Ubuntu 21 I am getting the following message when starting the CB server:

INFO: Initializing ProtocolHandler ["http-nio-8080"]
Jul 02, 2025 8:18:18 AM org.apache.catalina.util.LifecycleBase handleSubClassException

When launching code beamer through the internet browser I am getting Not Found 404 error.

Any help is welcome
