Hi @Nickmex

Welcome to the HP Support Community. I'd be happy to assist you

Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support. We appreciate your patience.

This error displays when the Embedded Web Server (EWS) has an expired certificate that is not accepted by the operating system. This certification is necessary to secure connections with AirPrint and Secure Internet Printing Protocol (IPPs).

To prevent the error, generate a new self-signed certificate from the EWS:

1. Enter the printer’s IP address in an internet browser address bar from any Windows desktop or notebook PC. The printer’s EWS opens.

   For more information on how to open the EWS, see Using the Printer Embedded Web Server (EWS).

   NOTE: 

   You must perform these steps from the desktop view in the EWS. The mobile view of the EWS does not have the Certificates menu option.

2. In the EWS, click the Network tab.

3. Click the plus sign next to Advanced Settings to expand the list, and then click Certificates.

4. Click Configure, select Create a New Self-Signed Certificate, and then click Next.

5. Click Finish. The printer generates a new certificate that defaults to 10 years from the valid date.

   

6. Close the EWS window

Hope this helps! Keep me posted.
