From the server log:
2025-02-07 09:31:28,549 INFO [ui.search.UserSearchContext] (https-jsse-nio2-443-exec-16-Administrator:[]) UserPerf Failed to fetch allowed cases
There are several factors that cause this issue:
If 1-4 is true and the end user tries to login to the master eDP server, then the blank screen occurs.
Workaround:
Instead of logging into the master eDP server, change the browser address over to the case home server that was last being used. This will then show the dialog window in regards to resuming last saved search. If needing assistance, create a support ticket and reference this technote.
This issue has been resovled in eDiscovery Platform 10.3.3.
Recommend to upgrade to this version or later.
