Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan
We would like to share some of the most frequently asked questions about HP Solution Center not working : Adobe Flash Player Error and Unable to Scan.

Microsoft Windows 10 (64-bit)

I have an HP color laserjet Pro MFP M479fnw, which stopped scanning last week. It was working fine before and just stopped working, and here is the error: The printer is unable to validate the server’s security certificate because the certificate is either self-signed or has been issued by an unknown authority. To enable the printer to validate the certificate, import trusted CA (Certificate Authority) certificates into the printer. Could you please assist if there is any way to fix it? I appreciate any help you can provide.
