Can't deploy a single function with v1.6

I’m having problems with deploying a single function.
I have no problem deploying my service with “sls deploy -v”. The size is around 12 MB.
However, every time I try to deploy a single function like this: (function name in sls.yml = create)

serverless deploy function --function create

I get:

Serverless: Deploying function: create...
Serverless: Packaging function: create...
Serverless: Uploading function: create (12 MB)...

  Serverless Error ---------------------------------------

     Connection timed out after 120000ms

  Get Support --------------------------------------------

  Your Environment Information -----------------------------
     OS:                 darwin
     Node Version:       7.7.1
     Serverless Version: 1.6.0

I can confirm that I do see a new zip file created in .serverless for this function, but it always times out!
