Trex Monitor - Preparation Failed

Hi,

I have configured a file system repository that I'm trying to index. I have installed KM Pack 3, and the crawler is working fine. But in indexing all the documents fail. Here are the queue details, same for all documents.

Return Code: 13502

Return Message: HTTP-Proxy: BadGateway

Document Status: Preparation Failed

Action: Index

Retry Count: 3

The repository seems to be working, as in I can access the files of the repository from the KM Content Tab.

Any ideas as to what am i doing wrong?

Regards,

Harsh
