SMP3 Admin cockpit is showing blank screen

Hi Experts,

I am seeing some strange behavior with SMP3(SP05 PL01) Admin cockpit. When i hit the URL (https://localhost:8083/Admin/) it is responding with a blank white screen. It was working till yesterday.

I have already tried with restarting SMP services, even restarting windows machine as well. I could see that Admin port 8083 is listening and SMP service is up and running (services.msc)

What went wrong?
