SSIS Packages are not executing on SQL Server Job

Hi Folks,

I set up a job to run a SSIS package in the MSDB, if right-click the package and run it, it completes successfully.

But when i run the job, The job just stays in the "Executing" state until I stop the job.

I have use SQL Server Agent service account and tried with Proxy account.

Error Message: Flat Files > Data Refresh > Load All >Daily reported: Unable to terminate process 7f08 launched by step 1 of job 0x82D5A7B1AF23274C853307B9CDAF0A69 (reason: Access is denied)

Note: The code was executed successfully earlier, from last two days we are facing the issue.

Appreciate your support!!!

Regards,
