After Enterprise Security Update I get connection reset by peer

[andresito123]

I upgraded to the latest ES app and now I get "The connection was reset" error when I am trying to connect to the web interface.

SplunkWeb likely was not able to start.

This is likely due to old advanced XML modules being left around. Delete the directory $SPLUNK_HOME/etc/apps/SA-Utils/appserver/modules/SOLNLookupEditor and restart SplunkWeb.
