HossUK,
Can you drill down to your <MyEclipse Software Dir>\configuration\config.ini file, and add a new property to the end of the file (make sure MyEclipse is closed down):
com.genuitec.pulse.client.wire.debug=true
This will generate a communications.log.gz in Genuitec/Common/logs. That file will include a trace of communication with the proxy server and any network failures that may be occurring. The file can grow quite large for successful operations but for failures it can be invaluable for detecting the failure in
network transfers.
