A newly installed agent will not start and there are no logs created in the log directory. The file nohup.err contained the following message:
unable to read raw key material
Workload Automation AE - 11.3.x
Platform - Linux, Unix, Windows.
The error message "unable to read raw key material" suggests a missing or damaged cryptkey.txt file from the agent's directory. Regenerate the file via the as_config command or copy the file, in binary mode, from a working system using the same encryption. Then the agent should be able to start.
