Hi!
One last big hurdle before fully operational is submitting to Deadline. The publish process errors at the “Submit Nuke to Deadline” step.
I have followed this guide and checked the forum and the internet for similar issues, but no solution yet.
The Deadline Web service is running correctly and I can connect to it in the browser, but somehow when submitting from the publish menu, it gets a broken response [200].
Here’s the whole error (I’ve hidden the project name and the IP address).
INFO: Using U:\projectname\sequences\kbr\kbr_0010\publish\workfile\workfile2d_prep\v003\KBR_kbr_0010_workfile2d_prep_v003.nk for render/export.

Hopefully someone has a quick fix 
Thanks!
