9.1.2 unable to add EMC Avamar

Hi All,
installed the new version on port 8083 and I'm not able to add Avamar Node, no meaningfull error.
The only error I see in the log is in sanslog.txt and it is
at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)

Any help greatly appreciated 'cause the instruction found here do not work.
