With all due respect, thank you for respond.
I would like to let you know that I have successfully fixed this error. The error was on my side.
Reasons for the occurrence of this error:
- Incorrect time in Local System
Briefly explaining error: My system was using two different timezone. One timezone is my Local timezone. Another is UTC(Univesal Timezone). The problem was not using 2 timezones. The problem was UTC's time in my system, it was 5hrs ahead from actual UTC.
So this makes Azure to think, the time for sandbox is completed. So it deactivated all the times.
Conclusion: The problem is resolved.
