LBP - Custom URL Failed for an unknown reason.

Hi, When trying to run an LBP report I get the following Error Message: "Custom URL Parameter Failed for an unknown reason" Lawson Global Support has not been able to assist thus far and the only article ID:557222 I found did not resolve my problem. After hours of diagnosing if it is a Port issue, URL settings issue, IIS websphere issue, it appears that LBP cannot communicate with LBI. The LBP reports are lawson solution pack reports that were deployed successfully some time ago. Both LBI and LBP are on the same server therefore it is difficult to troubleshoot network traffic. I was told that although my problem is the LBP reports the problem is more likely on the LBI side because LBP and LBI talk to each other thru a parameter servlet setting on the LBP server which sends info back to LBI. Logs were not very helpful, but there was a consistent message about Not able to connect in the systemout.log file. If anyone has experienced this and can advise me of a solution or direction on what else to check, I would appreciate it very much. thank you,
