OpManager DE Error Discovering Device

OpManager DE Error Discovering Device

I have recently removed several devices from OpManager as they were not discovered correctly, after deleting them, I can now not re-add them. Recieving the following message "Entries for the device are either partially added or removed.Click [here...] to remove and readd the device"

I have tried to access the fix at https://opmanageree.wiki.zoho.com/Remove-stray-entries-from-database.html but am told that "opmanageree.wiki.zoho.com is not accessible by you."

Could someone please provide a fix/link that I can access to resolve this issue?

Many Thanks

James
