The host I am trying to run a job on is able to successfully communicate back and forth with my Foreman instance (I’ve checked with tcpdump).
The yggdrasild service is enabled and running on the target host (installed from the katello-pull-transport-migrate package).
I’ve enabled pull-based transport on my smart proxy using the --foreman-proxy-plugin-remote-execution-script-mode pull-mqtt option and I have enabled the remote execution plugin with the --enable-foreman-proxy-plugin-remote-execution-script option.
