I am running PRTG version 126.96.36.1993. I recently moved the PRTG installation to a new server, following the migration instructions (http://www.paessler.com/knowledgebase/en/topic/413-how-can-i-move-migrate-my-prtg-installation-to-another-computer).
If I connect via the web interface everything looks great. All of my sensors, history, notifications, etc were migrated and all functionality is there. However, when I use the PRTG GUI application for Windows I am unable to see any graphs. This is from any machine that I install the GUI onto. If I hit the "Live Graph" tab I see the all of the current sensor results listed, but the graph remains blank. I've also noticed that on the "Overview" tab the Status of the sensors shows a grey question mark, stating, "No data". However, the icons are green everywhere else, and I can see the up to the minute data, so I know it is there. It also seems to take a very long time to bring up any of the tabs for a particular sensor, making it seem like it's waiting for data that never arrives.
Has anyone else encountered problems with the Windows app after a migration? I've tried the basic uninstall / reinstall on my machine and others without any luck.
Any suggestions would be appreciated. Thanks!
