Issue in integrating FitNesse with Appian - (1) Unable to invoke Appian site for AUT. (2) Slim server died error...

Hi,

We installed and configured the FitNesse for purpose of working with Appian sites to perform some AUT. Hence we configured with given Two Example by adding the appian url with version and username but getting following errors, cannot launch the appian site.

1. At first setup and launch of FitNesse worked but had issue in invoking the Appian site and throws following error

2. Unable run the Test itself also and throws following slim error message;  This was done after closing browser and than restarted the batch job of FitNesse & ran the test.

Could not complete testing: fitnesse.slim.SlimError: Error SLiM server died before Header Message could be read. Unable to start test system 'slim': fitnesse.slim.SlimError: Error SLiM server died before Header Message could be read.
