Product: MFP P57750

Hi,

 

When I try to add the .cer (or .pem or .der) certificate to the printer to be able to connect to wifi, the printer shows the following error:

 

"The certificate is not RFC 5280 compliant."

 

We tried the solutions given on https://h30434.www3.hp.com/t5/LaserJet-Printing/The-certificate-is-not-RFC-5280-compliant/m-p/788659... but there was no success. We generated our radius certificate from letsencrypt.org recently. Please help.

 

Thanks
