Printer cannot communicate with the Cloud Fleet Management portal after deployment

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.

North American Data Center—The web address of the login screen starts with https:\\idp.us.iss.lexmark.com.

Make sure that the printer firmware is updated to support Transport Layer Security (TLS) version 1.2
