HTTP-REST configuration lost after reboot

I'm usint vRealize Orchestrator 6.0.2 and I've configured two HTTP-Rest hosts with several operations.

Every time  I reboot the vRO server, something happend with the HTTP-Rest configuration. Sometimes a host is lost, or the operations, or everything.

I've reconfigured all hosts and operations and reboot again and maybe a host is duplicated but one has no operations.

I've deleted all configuration files in the resources tab and configure all again with the same result.

Any ideas?

Thanks,

D.
