Hi,
I'm new to Solarwinds and have come across this problem. I've read other users' posts on here and have tried everything suggested but I've still not managed to fix this problem
I've checked the account limitations and the devices that I am having the problems with are all allowed both in the user account and the view. Within the same view some sites are fine, but others are returning this error when I try to view them.
I've tried deleting and readding the devices but this has made no difference.
I've also tried logging in as an administrator and removing all limitations but still no joy
Does anyone know how to fix this please? Any help would be much appreciated 
Thanks
