Please update to version 3.6.7 by downloading from here: https://camwebapp.com/download/
I’d suggest uninstalling the previous version before installing the new version as a clean install rather than updating it.
Please let me know if the issue is resolved after this.
Thanks.Adrian Mitchell commented
same here - was fine until about 10 days ago - and it is fine for a while after I turn on the machine - but once it starts it is popping the CAM Settings Upload Failed message every 15 seconds and it doesn't stop until i close CAM software - i have version 3.5.90 and checkign for updates does nothing so I assume there aren't any
