There are six printers connected to the network via Pi
boards using Octopi and OctoPrint. Each have their own static IP and function as they should in OctoPrint. Using the Polar Cloud plug-in the printers originally registered
and loaded into Polar Cloud as expected. Once power was cycled on the printers,
their status became OFFLINE in Polar Cloud. I have not been able to
bring them back online. I have looked for every connection setting in OctoPrint and Polar Cloud, reloaded, reset and even tried to re-register a printer. No go in all cases. Could there be a firewall issue? Any ideas??
