Printer cannot communicate with the Cloud Fleet Management portal after deployment

Enable the DHCP setting for the printer, allow auto DNS configuration, and allow the Lexmark Cloud Services domains to use port 443.

Try one or more of the following:

Make sure that the Dynamic Host Configuration Protocol (DHCP) setting is enabled and that auto‑configuration of the Domain Name System (DNS) setting is allowed.

From the Embedded Web Server, click

Settings

Network/Ports

Ethernet

, and then, from the IPv4 section, select

Enable DHCP

If you use a static IP address, then make sure that you set the static IP address only after the DNS setting is auto‑configured.

If a firewall is in place, then make sure that the Lexmark Cloud Services domains are allowed to use port 443.

The domains depend on the Lexmark Cloud Services data center. To determine the data center for your organization, use the web address of the login screen. For more information, see the Lexmark Cloud Services New and Changed Functionality document.
