Hey,

I'm trying to run the sample.py from the Canonical Program example with Python 3.6.1 and dispy==4.7.6 running on OSX 10.12.4 and Im getting this error:

Seems to be OK on Ubuntu 16.4. Must be an OSX thing...?

This may be because the host name can't be resolved to IP address. Check DNS (domain name server) settings and point it to (correct) server? Alternately, you can specify the IP address of your OS X client with ip_addr parameter to JobCluster.

Have you tried above / something that fixed it?
