Maya renders are not happening on muster


I am trying to submit render from Muster Console (Render Farm) of a Maya file. But the file is getting qued in Muster repository but the render is not happening. If I go to the render blade and start the render using cmdline, then it is getting rendered.

Can anyone put some light into it.
Maya 2018 rendering on VRay render engine and Muster v9.0.14
