Ubuntu MaaS ssl error vmware vcenter 6 connection

Ubuntu Server 16.04.1
MaaS 2.0 Beta 3
vmware vcenter 6

pyvmomi-5.5.0.2014.1.1 which is installed manually for python 3 because i read it would fix my problem

this is the error I'm getting:

i read several old posts from last year on how on to fix that. but none of them work or even point me to the files which i have to edit.

somebody please point me in the right direction so that i can deploy my vmware nodes.

i tried MaaS 1.8/1.9 and now 2.0 and each version has problems that cannot be solved or are solved in future version but bring now bugs with it.
