Facing Login Timeout issues in SSIS Package

SSIS jobs are getting failed frequently with the below error message. Although it restarts and runs successfully in the next run, SSIS jobs are getting failed sporadically in the subsequent runs. These issues were happening after our SQL Server was patched with KB4338824 and KB4338815 updates. Any help?
