Possible Solutions

On investigating the logs in /var/log/cortex/application.log i noticed the following entry

2022-11-28 14:35:40,025 [WARN] from org.thp.cortex.services.WorkerSrv in application-akka.actor.default-dispatcher-7 - **Worker path (/opt/Cortex-Analzers/responders) is not found**

It appears that there is a typo in the code in org.thp.cortex.services.WorkerSrv--akka.actor.default-dispatcher-7.

To confirm, this I did the following

1. Create the directory /opt/Cortex-Analzers/responders.
2. Change the owner to cortex:cortex recursively.
3. Change to /opt/Cortex-Analzers/responders/ directory
4. Link the /opt/Cortex-Analzers/responders to the correct directory of /opt/Cortex-Analyzers/responders/

sudo ln -s /opt/Cortex-Analyzers/responders/ .

Complementary information

Responders are now available to be enabled
