Hi Hans,
Some general notes;
First of all it would be best to separate the optimizer to a different
machine, even if a VM. This is needed since the optimizer is based on
OptaPlanner which uses all the memory it can get for optimizations.

To the point this is either something going wrong in the installation or
an access issue. Access can be caused due to root certificate not
trusted by the browser. If you use
wget https://ovirt.optimizer:8080/ovirt-optimizer/result/
do you get an issue / warning on unknown certificate?
