Hyperion 11.2 Planning Error on install

I have just installed Hyperion Planning, ran the validation check with no issues reported. The Hyperion Planning login screen appeared but when I tried to login the next screen came back with 'error occurred'. Checked the HyS9Planning_epmsystem1-sysout log, this contained the following error messages:

<Error> <HTTP> <BEA-101017> <[[email protected][app:PLANNING module:HyperionPlanning path:null spec-version:3.1 version:11.1.2.0]] Root cause of ServletException.java.io.IOException: An established connection was aborted by the software in your host machineat sun.nio.ch.SocketDispatcher.write0(Native Method)

Any help would be much appreciated.
