[Spce-user] Error installing spce 5.5.2

[Alejandro Grijalba]

Hi. I'm trying to install Spce version 5.5.2 from latest ISO and I get 
some error.
Server is VMware, 1vCPU, 12GB of RAM.

The log in /tmp/deployment-installer-debug.log says:

Despite the error I have verified that grafana is listening on port 
4000, i can test connect using telnet.
It looks like "grafana" takes too long to start and then fails, without 
retrying.

May this be a timing issue?
