When you have installed both Symantec Endpoint Protection Manager and DLO Server 7.5 you can meet a port conflict. Both application use tomcat with default https port 8443.
i.e. if you have installed SEPM 12.1 and upgrade DLO to 7.5 you may encounter problems with logging to SEPM console like:
- Server Certificate is not present in your trusted store
- Unexpected server Error
Problem disappears after service Mindtree StoreSmart Dedupe Server (tomcat7.exe) is stopped.
DLO 7.5 have new feature: Dedupe Server, which uses tomcat on https port 8443, the same port that uses tomcat in SEPM.
I solved the problem by change DLO dedupe server port to 8443. I've edited "C:\Program Files\Symantec\Symantec DLO\Dedupe\Tomcat\conf\server.xml" file in notepad. I've updated all entries of "8443" to i.e. "8449".
Other possible solution is change the SEPM port. You can do it by "Management Server Configuration Wizard"
