appian upgrade from 20.1 to 20.3

Hi all:

  When I upgrade appian from 20.1 to 20.3 with the upgrade guide https://docs.appian.com/suite/help/21.3/Upgrade_Guide.html#custom-spring-security-configurations;

  After I upgrade step by step as step 8 Start Appian,(We use systemd to start appian, ) we can systemctl start appian-services successfully , but when I use status script to show the status of cluster , it prints that exectaion 02 of 3 nodes are starting but not running and any other engines status are OK). when I try to search logs, there are nothing error on services_manager.log or executation02.log or executaion02.err. can anyone advise me how to fix it
