Xerox says our copiers are not communicating with them
Product Name: WorkCentre EC7836/EC7856
Operating System: Windows 10 x64
We have gotten notices that for the last 60 days, our copiers are not communicating with Xerox. However, when I go into the machine settings and Synchronize, the copier tells me "Communication with Xerox successful!" Maybe there's an issue where if the copier initiates the communication it works, but if Xerox does, it's blocked?
Can anyone let me know what else I should be checking, or if I need to verify that a site needs to be whitelisted?
