Cinema 4D 21 render stuck on 0%

Hi

We have a few jobs to be rendered on our farm from Cinema4D 21.

Two jobs have been submitted so far, but they are stuck ‘rendering’ on 0%.

Three render slaves have been auto-assigned to render and each of them have the same issue.

I’ve rebooted one of the render nodes/slaves and nothing has changed.

No errors have ben logged alongside them, as they render.

These jobs have been resubmitted a few times over the past couple of days and no improvements have been made on their progress.

Renders from other applications (Nuke, etc.) and have rendered as normal.

Could this a licensing issue? or a fault in submitting the job to the farm?

Any suggestions on why this is happening, and how to resolve it would be much appreciated

Thanks

did you license c4d command line on those machines? (Annoyingly it needs licensing separately)

if you run the following command in a command prompt (cmd)
C:\Program Files\Maxon Cinema 4D R21\Commandline.exe
does it bring up the license info?

likely it’s request the license info or error on it
