CA invalid SSL error

MariusVoicu79

Hello,

I have a problem with the CA issued by zyxel. When accessing the firewall ATP200 the browser says that is not valid(not secure connection via HTTPS). The CA is valid until 2034 and is imported in the Windows Client Trusted CA. What am I missing?

Thanks!

Hi @MariusVoicu79 ,

Greeting Forum, Not only windoes must have trusted CA, but also the CN name in the certificate msut be matched when you input the URL. For example:

1)I created the self-sign CA with CN: www.kevin.com

2)And select my certificate for HTTPS Serve CA

3)I can connect HTTPS without warining.

(It have to use Domain: www.kevin.com)

Thank you

Thnks! I have already read about selfsigned CA.
