HP Office DeskJet 8710 scan to email - gmail can't validate certificate

[snorgplat]

I've been trying to setup Scan to Email via gmail with my Deskjey 8710 and continue to get the error message: 

"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.

To import the certificate, go to the Certificates page, and then follow the onscreen instructions."

Here's the settings I've been working with:

Default From: myemail@gmail.com

Default Display Name: My name

SMTP Server: smtp.gmail.com

SMTP Port: 465

Always use secure connection (SSL/TLS) - yes

Validate Server Certificate - yes

Maximum Size of Email: Unlimited

Server Authentication - Server requires authentication:

User Name: My user name

Password: My password

Then when I do my outgoing email test I get the above error. 

I do not have 2-factor authentication setup, and I have turned on "use less secure apps" in my gmail settings. I have been unable to find any other potential fixes via search. Hopefully you're able to help!

Thanks!

Hi,

Uncheck the box next to Validate Server Certificate and test again, that should resolve the error.
