Assuming DNS settings are correct, remove whatever is entered as the devices domain name @ "Connectivity>Ethernet>DNS>Domain Name:". Just leave the field blank. That alone solved my proxy error. I had other issues occurring so I updated firmware to match the versions listed in the enhancement document at the URL below;
Newer versions are listed there than are available from the Xerox support site/devices' updater for whatever reason. Let me know if that helps you or not!
Thank you for letting me know. I am forwarding the email now.
Please let me know if you do not receive it shortly.
Thank you for your message.
I am sending you a separate email with some suggestions.
Versalink C70XX MFPs Firmware 57.42.1
This started with one MFP stating that EIP settings were incorrect when using Scan to Cloud Email. The service had been working fine for over a year up to that point. When I couldn't find any issues, I updated firmware to current and now see a "Service Unavailable, check connection/proxy settings" error when opening any app and the app gallery now claims there is no internet connection at all. I am able to successfully connect to all devices from the Appgallery website and perform actions so the connection is there.
In testing I upgraded firmware on a verified working MFP and it now has the same errors. The MFPs running older firmware (57.31.81) are still working without issue.
I tried a full reset on one device and reconfigured it from scratch with no change.
*I run embedded accounting software (Papercut) which hasn't had/caused any issues up to now but I upgraded it to current just in case. Still no luck.
