Sandbox Plugin issue

Hi guy,

I render all the tasks normally, but it suddenly turns out error and stops working. Anyone, please help me resolve this issue, thanks a lot.

I’m using 3dsMax 2019 and Vray 5 to submit the render.


Failed to load the plugin because: Could not initialize the plugin sandbox (Deadline.Plugins.PluginException)

Hi VuTranThien,

I had the same issue very recently.
Though in my case the firewall blocked part of the communication between the repository and the deadline client. This lead to some nodes being able to render, whilst others were causing errors.

So maybe you’ll have to look into your firewall settings.


Hi there VuTranThien. Just wondering if you figured this out. I am suddenly having the same issue. Fairly new install, but was working fine last week.
