All SOI reports fail with the error message similar to: "Failed to open the connection: Services Summary"
The problem is with Universe connection mapping to wrong DB, due to this the reports throwing this exception.
In order to correct this problem...
1) Make sure CABI Universe is connecting to SOI DB (SAMStore) and restart CABI Services.
