Ok, I just tried again, and it doesn't work (but it doesn't fail with out of memory) - I wonder if Google has detected that the same certificates are being used by multiple MAC addresses and has blocked them?
Could you try creating your own certificates and keys using the instructions here:

You don't need server certificates, just the client certificates.
