CAD worker "Failed to register Windchill server --15" error

[Dobrisa]

We're having issues with publishing Creo and Solidworks files on a test environment with the latest Creo Adapters. 

The workers are set up, configured and seemingly functioning. For both Creo and Solidworks, the "Test Server" comes back successful but on publishing we get an error.

I've looked thru the community here and there are a couple of topics dealing with the --15 error. I tried implementing some of the solutions but no luck. 

Can someone point me in the right direction?

Did publishing just start failing or has it never worked at all on this test server?  Have you tried starting the worker daemon manually instead of as a service (just for testing? )

Update: we got the Creo worker to publish. After starting the GS Worker Daemon separately and changing the log on info it started working. 

Now the Solidworks worker is still not working. This one hasn't worked at all. Trying to just run it separately thru the swworker.bat, it starts up fine but when a publish job comes, the error says that there isn't a connected worker.
