upgrade Web_Scheduling_2016_SP9_UP4_1 issues (web service stopped)

SOLVED

I am upgrading the new version of SedApta Web Scheduling,all installation procedures are fine and no error messages.

Restart the VM and logon Web Scheduling with MODX3, it pops up " Unable to reach Web Scheduler Service, check Web.config connection parameters."

  

From Task Manager I found SedAptaSchedulerService stopped and it cannot be restart by manually.

Does anybody know how to fix it? Thanks.
