I have upgrade to 4.2 and have some problem getting everithing up and running again.

The upgrade was made from latest 4.1. For now the engine dashboard can be access but all hosts, data center are all the status to "Not responsive" ... 

for now the only thing i found is 

ERROR ssl handshake: SSLError, address:

from a systemctl status vdsmd

Any help would be appreciated
