Resolution

This issue is resolved in vRealize Log Insight 8.10.2 (build number 21145187)

Workaround:
To work around the issue:

1. Download the Bootstrapper.tar.gz  file attached to this article
2. Using SCP software such as WinSCP or FileZilla, copy the file to the /tmp directory of the primary node
3. SSH to the primary node as root
4. Stop the Log Insight service

systemctl stop loginsight

5. Change to this directory

cd /usr/lib/loginsight/application/3rd_party/apache-tomcat-8.5.82/webapps/ROOT/WEB-INF/classes/com/vmware/loginsight/web

6. Backup the old files to the root directory

mv bootstrap ~/bootstrap_old

Note: This backup file can be removed after some time, once the cluster is confirmed to be healthy

7. Make a new directory and navigate there

mkdir bootstrap && cd bootstrap

8. Extract the Bootstrapper.tar.gz file

tar xzf /tmp/Bootstrapper.tar.gz

9. Start the Log Insight service

systemctl start loginsight

Note: Wait several minutes to allow the service to come up, and then verify the availability of the primary node's UI

10. Re-configure the vIDM Integration from Administration->Configuration->Authentication->VMware Identity Manager
11. Restart the Log Insight service on the primary node once more, and verify the availability of the UI after several minutes

systemctl restart loginsight
