We have observed the Network Hierarchy management application suddenly stopped working, while taking backup or uploading it is throwing error "Something went wrong! Unknown error occured; see logs for more detail"

Note : Previously the application used to work perfectly without any issue.

we have tried all possible options as below.

1. changing the FQDN from upper case to lower.
2. Uninstall and reinstallation of the application.
3. Patch upgrade
4. raised the case with QRadar support but not support from them.

Please assist as it is very difficult to update multiple network segment in Hierarchy.

I assume you are using 7.4+ ?

I have not been able to get this app to work past 7.3 due to the way the applications utilize certificate services now.
