SAP Browser Access Error - Blue empty screen

Hello,

SB1 9.2 PL03 new installation over MS WIN SRV 2012 R2.

New server, no other services on the server AT ALL.

Tried to run the browser access after installation, logon was successful but afterwards I'm getting blue screen which isn't loading anything (though the red "flower" appeared for a couple of seconds)

Screenshot attached.

Any suggestions for anyone for the cause?

1. Tried restart Gatekeeper + SLD.

2. the access is internally from the SB1 server itself (and will be only this kind of access forever)

Thanks,

Or.
