Cannot login first run Opmanager 11.3

Cannot login first run Opmanager 11.3

Downloaded OpManager 11.3 free edition and installed it fresh under Windows Server 2012R2 using PGSQL. Installation gone well but I cannot login through a web browser ( IE or Chrome). The browser is stuck at the License Activation Details page in a waiting loading loop.

Is anyone else experiencing this issue? Any help would be appreciated.

Thanks,
