I had a proxy fail at a remote location and I reloaded. I have installed back at the remote site with the same IP and prefailure information but my servers are not reporting to it. The Main Site unit is showing it as online and reporting to it.(See Attached) I have checked the config on the servers and they match the proxy. I am seeing the following error - please see attached.

Not sure what I am doing wrong on what the issue is but it is urgent I get this issue resolved.
