  1. Wait a moment and try again
  2. Wait a bit longer and try a second time

If the error persists, examine the log file under /home/tomcat/version/logs/catalina.out

The file can be accessed via Other > File Manager

To kill all Tomcat process, start an SSH session and issue:

pkill -9 java


Some common causes of errors are:

  1. Tomcat failed to stop
  2. Deploying an unsupported jar
  3. Deploying a version mis-matched jar
  4. A second session was spawned, causing the port to be occupied.
