Devices unpolled error

Help
1

I keep getting the error;

“Devices unpolled, It appears as though you have some devices that haven’t completed polling within the last 15 minutes, you may want to check that out :)”

When I go into the link, all my devices look to have polled in the last 15 minutes and they also look to not have taken too long.

Any ideas why I am getting this error?

Looks like the MQSQL database and the librenms timezones are out of sync. mysql has not adjusted to BST
