Hello, has anyone has saw this problem before?
Few things to start with :
1) Can you please share BL-A installation Log.(bl2atrium_install_log.txt)
2) Have a look at logs <BL-A installation Directory>\Logs\extloader\Logs\ExtLoaderLogs\
3) Is BDSSA DB reachable from CMDB
4) BL-A create two entry in shared:application_properties form in CMDB with Application ID : OI-D713AC3B08AD47A39C9A17107C500BD8 . Uninstall BL-A , Delete both entry from shared:application_properties. And try reinstallation.
